/** \brief Template function for accurate conversion from one primitive type to another.
The function saturate_cast resembles the standard C++ cast operations, such as static_cast\() and others. It perform an efficient and accurate conversion from one primitive type to another (see the introduction chapter). saturate in the name means that when the input value v is out of the range of the target type, the result is not formed just by taking low bits of the input, but instead the value is clipped. For example:
```
 uchar a = saturate_cast<uchar>(-100); // a = 0 (UCHAR_MIN)
 short b = saturate_cast<short>(33333.33333); // b = 32767 (SHRT_MAX)
 
```
Such clipping is done when the target type is unsigned char , signed char , unsigned short or signed short . For 32-bit integers, no clipping is done.
When the parameter is a floating-point value and the target type is an integer (8-, 16- or 32-bit), the floating-point value is first rounded to the nearest integer and then clipped if needed (when the target type is 8- or 16-bit).
Parameters:

v - Function parameter.

\brief OpenCV will try to set the number of threads for the next parallel region.
If threads == 0, OpenCV will disable threading optimizations and run all it's functions sequentially. Passing threads \< 0 will reset threads number to system default. This function must be called outside of parallel region.
OpenCV will try to run its functions with specified threads number, but some behaviour differs from framework: - TBB - User-defined parallel constructions will run with the same threads number, if another is not specified. If later on user creates his own scheduler, OpenCV will use it. - OpenMP - No special defined behaviour. - Concurrency - If threads == 1, OpenCV will disable threading optimizations and run its functions sequentially. - GCD - Supports only values \<= 0. - C= - No special defined behaviour.

Parameters:

nthreads - Number of threads used by OpenCV.

If there is any tbb::thread_scheduler_init in user code conflicting with OpenCV, then function returns default number of threads used by TBB library. - OpenMP - An upper bound on the number of threads that could be used to form a new team. - Concurrency - The number of threads, that OpenCV will try to use for parallel regions. - GCD - Unsupported; returns the GCD thread pool limit (512) for compatibility. - C= - The number of threads, that OpenCV will try to use for parallel regions, if before called setNumThreads with threads \> 0, otherwise returns the number of logical CPUs, available for the process.

Deprecated. Current implementation doesn't corresponding to this documentation.
The exact meaning of the return value depends on the threading framework used by OpenCV library: - TBB - Unsupported with current 4.1 TBB release. Maybe will be supported in future. - OpenMP - The thread number, within the current team, of the calling thread. - Concurrency - An ID for the virtual processor that the current context is executing on (0 for master thread and unique number for others, but not necessary 1,2,3,...). - GCD - System calling thread's ID. Never returns 0 inside parallel region. - C= - The index of the current parallel task.

\brief Returns the index of the currently executed thread within the current parallel region. Always returns 0 if called outside of parallel region.

getCPUTickCount
```
@Namespace(value="cv")
 @Cast(value="int64")
public static long getCPUTickCount()
```
\brief Returns the number of CPU ticks.
The function returns the current number of CPU ticks on some architectures (such as x86, x64, PowerPC). On other platforms the function is equivalent to getTickCount. It can also be used for very accurate time measurements, as well as for RNG initialization. Note that in case of multi-CPU systems a thread, from which getCPUTickCount is called, can be suspended and resumed at another CPU with its own counter. So, theoretically (and practically) the subsequent calls to the function do not necessary return the monotonously increasing values. Also, since a modern CPU varies the CPU frequency depending on the load, the number of CPU clocks spent in some code cannot be directly converted to time units. Therefore, getTickCount is generally a preferable solution for measuring execution time.

checkHardwareSupport
```

```
\brief Returns true if the specified feature is supported by the host hardware.
The function returns true if the host hardware supports the specified feature. When user calls setUseOptimized(false), the subsequent calls to checkHardwareSupport() will return false until setUseOptimized(true) is called. This way user can dynamically switch on and off the optimized code in OpenCV.

Parameters:

feature - The feature of interest, one of cv::CpuFeatures

```
\brief Enables or disables the optimized code.
The function can be used to dynamically turn on and off optimized dispatched code (code that uses SSE4.2, AVX/AVX2, and other instructions on the platforms that support it). It sets a global flag that is further checked by OpenCV functions. Since the flag is not checked in the inner OpenCV loops, it is only safe to call the function on the very top level in your application where you can be sure that no other OpenCV function is currently executed.
By default, the optimized code is enabled unless you disable it in CMake. The current status can be retrieved using useOptimized.

Parameters:

onoff - The boolean flag specifying whether the optimized code should be used (onoff=true) or not (onoff=false).

useOptimized
```
@Namespace(value="cv")
 @Cast(value="bool")
public static boolean useOptimized()

\brief Returns the status of optimized code usage.
The function returns true if the optimized code is enabled. Otherwise, it returns false.

\brief Initializes a random number generator state.
The function initializes a random number generator and returns the state. The pointer to the state can be then passed to the cvRandInt, cvRandReal and cvRandArr functions. In the current implementation a multiply-with-carry generator is used.

Parameters:

seed - 64-bit value used to initiate a random sequence

```
\brief Sets the channel of interest in an IplImage.
If the ROI is set to NULL and the coi is *not* 0, the ROI is allocated. Most OpenCV functions do not* support the COI setting, so to process an individual image/matrix channel one may copy (via cvCopy or cvSplit) the channel to a separate image/matrix, process it and then copy the result back (via cvCopy or cvMerge) if needed.

Parameters:

image - A pointer to the image header

coi - The channel of interest. 0 - all channels are selected, 1 - first channel is selected, etc. Note that the channel indices become 1-based.

                                 CvRect rect)
```
\brief Sets an image Region Of Interest (ROI) for a given rectangle.
If the original image ROI was NULL and the rect is not the whole image, the ROI structure is allocated.
Most OpenCV functions support the use of ROI and treat the image rectangle as a separate image. For example, all of the pixel coordinates are counted from the top-left (or bottom-left) corner of the ROI, not the original image.

Parameters:

image - A pointer to the image header

rect - The ROI rectangle

cvResetImageROI
```
public static void cvResetImageROI(IplImage image)
```
\brief Resets the image ROI to include the entire image and releases the ROI structure.
This produces a similar result to the following, but in addition it releases the ROI structure. :
```
    cvSetImageROI(image, cvRect(0, 0, image->width, image->height ));
    cvSetImageCOI(image, 0);
```
Parameters:

image - A pointer to the image header

\brief Initializes a pre-allocated matrix header.

This function is often used to process raw data with OpenCV matrix functions. For example, the following code computes the matrix product of two matrices, stored as ordinary arrays:


    double a[] = { 1, 2, 3, 4,
                   5, 6, 7, 8,
                   9, 10, 11, 12 };

    double b[] = { 1, 5, 9,
                   2, 6, 10,
                   3, 7, 11,
                   4, 8, 12 };

    double c[9];
    CvMat Ma, Mb, Mc ;

    cvInitMatHeader(&Ma, 3, 4, CV_64FC1, a);
    cvInitMatHeader(&Mb, 4, 3, CV_64FC1, b);
    cvInitMatHeader(&Mc, 3, 3, CV_64FC1, c);

    cvMatMulAdd(&Ma, &Mb, 0, &Mc);
    // the c array now contains the product of a (3x4) and b (4x3)

Parameters:: mat - A pointer to the matrix header to be initialized; rows - Number of rows in the matrix; cols - Number of columns in the matrix; type - Type of the matrix elements, see cvCreateMat .; data - Optional: data pointer assigned to the matrix header; step - Optional: full row width in bytes of the assigned data. By default, the minimal possible step is used which assumes there are no gaps between subsequent rows of the matrix.

cvDecRefData
```
public static void cvDecRefData(CvArr arr)
```
\brief Decrements an array data reference counter.
The function decrements the data reference counter in a CvMat or CvMatND if the reference counter
pointer is not NULL. If the counter reaches zero, the data is deallocated. In the current implementation the reference counter is not NULL only if the data was allocated using the cvCreateData function. The counter will be NULL in other cases such as: external data was assigned to the header using cvSetData, header is part of a larger matrix or image, or the header was converted from an image or n-dimensional matrix header.

Parameters:

arr - Pointer to an array header

cvIncRefData
```
public static int cvIncRefData(CvArr arr)
```
\brief Increments array data reference counter.

\brief Initializes sparse array elements iterator.

The function initializes iterator of sparse array elements and returns pointer to the first element, or NULL if the array is empty.

Parameters:: mat - Input array; mat_iterator - Initialized iterator

cvGetNextSparseNode

public static CvSparseNode cvGetNextSparseNode(CvSparseMatIterator mat_iterator)

\brief Returns the next sparse matrix element

The function moves iterator to the next sparse matrix element and returns pointer to it. In the current version there is no any particular order of the elements, because they are stored in the hash table. The sample below demonstrates how to iterate through the sparse matrix:


    // print all the non-zero sparse matrix elements and compute their sum
    double sum = 0;
    int i, dims = cvGetDims(sparsemat);
    CvSparseMatIterator it;
    CvSparseNode* node = cvInitSparseMatIterator(sparsemat, &it);

    for(; node != 0; node = cvGetNextSparseNode(&it))
    {
        int* idx = CV_NODE_IDX(array, node);
        float val = *(float*)CV_NODE_VAL(array, node);
        printf("M");
        for(i = 0; i < dims; i++ )
            printf("[%d]", idx[i]);
        printf("=%g\n", val);

        sum += val;
    }

    printf("nTotal sum = %g\n", sum);

Parameters:: mat_iterator - Sparse array iterator

cvGetElemType
```
public static int cvGetElemType(@Const
                                CvArr arr)
```
\brief Returns type of array elements.
The function returns type of the array elements. In the case of IplImage the type is converted to CvMat-like representation. For example, if the image has been created as:
```
    IplImage* img = cvCreateImage(cvSize(640, 480), IPL_DEPTH_8U, 3);
```
The code cvGetElemType(img) will return CV_8UC3.
Parameters:

arr - Input array

cvGetDims
```
public static int cvGetDims(@Const
                            CvArr arr,
                            IntPointer sizes)
```
\brief Return number of array dimensions
The function returns the array dimensionality and the array of dimension sizes. In the case of IplImage or CvMat it always returns 2 regardless of number of image/matrix rows. For example, the following code calculates total number of array elements:
```
    int sizes[CV_MAX_DIM];
    int i, total = 1;
    int dims = cvGetDims(arr, size);
    for(i = 0; i < dims; i++ )
        total *= sizes[i];
```
Parameters:

arr - Input array

sizes - Optional output vector of the array dimension sizes. For 2d arrays the number of rows (height) goes first, number of columns (width) next.

```
\brief Return pointer to a particular array element.
The functions return a pointer to a specific array element. Number of array dimension should match to the number of indices passed to the function except for cvPtr1D function that can be used for sequential access to 1D, 2D or nD dense arrays.
The functions can be used for sparse arrays as well - if the requested node does not exist they create it and set it to zero.
All these as well as other functions accessing array elements ( cvGetND , cvGetRealND , cvSet , cvSetND , cvSetRealND ) raise an error in case if the element index is out of range.

Parameters:

arr - Input array

idx0 - The first zero-based component of the element index

type - Optional output parameter: type of matrix elements

\brief Returns matrix header for arbitrary array.
The function returns a matrix header for the input array that can be a matrix - CvMat, an image - IplImage, or a multi-dimensional dense array - CvMatND (the third option is allowed only if allowND != 0) . In the case of matrix the function simply returns the input pointer. In the case of IplImage\* or CvMatND it initializes the header structure with parameters of the current image ROI and returns &header. Because COI is not supported by CvMat, it is returned separately.
The function provides an easy way to handle both types of arrays - IplImage and CvMat using the same code. Input array must have non-zero data pointer, otherwise the function will report an error.
\note If the input array is IplImage with planar data layout and COI set, the function returns the pointer to the selected plane and COI == 0. This feature allows user to process IplImage structures with planar data layout, even though OpenCV does not support such images.

Parameters:

arr - Input array

header - Pointer to CvMat structure used as a temporary buffer

coi - Optional output parameter for storing COI

allowND - If non-zero, the function accepts multi-dimensional dense arrays (CvMatND\*) and returns 2D matrix (if CvMatND has two dimensions) or 1D matrix (when CvMatND has 1 dimension or more than 2 dimensions). The CvMatND array must be continuous.

```
\brief Returns image header for arbitrary array.
The function returns the image header for the input array that can be a matrix (CvMat) or image (IplImage). In the case of an image the function simply returns the input pointer. In the case of CvMat it initializes an image_header structure with the parameters of the input matrix. Note that if we transform IplImage to CvMat using cvGetMat and then transform CvMat back to IplImage using this function, we will get different headers if the ROI is set in the original image.

Parameters:

arr - Input array

image_header - Pointer to IplImage structure used as a temporary buffer

                                   IntPointer new_sizes)
```
\brief Changes the shape of a multi-dimensional array without copying the data.
The function is an advanced version of cvReshape that can work with multi-dimensional arrays as well (though it can work with ordinary images and matrices) and change the number of dimensions.
Below are the two samples from the cvReshape description rewritten using cvReshapeMatND:
```
    IplImage* color_img = cvCreateImage(cvSize(320,240), IPL_DEPTH_8U, 3);
    IplImage gray_img_hdr, *gray_img;
    gray_img = (IplImage*)cvReshapeMatND(color_img, sizeof(gray_img_hdr), &gray_img_hdr, 1, 0, 0);
    ...
    int size[] = { 2, 2, 2 };
    CvMatND* mat = cvCreateMatND(3, size, CV_32F);
    CvMat row_header, *row;
    row = (CvMat*)cvReshapeMatND(mat, sizeof(row_header), &row_header, 0, 1, 0);
```
In C, the header file for this function includes a convenient macro cvReshapeND that does away with the sizeof_header parameter. So, the lines containing the call to cvReshapeMatND in the examples may be replaced as follow:
```
    gray_img = (IplImage*)cvReshapeND(color_img, &gray_img_hdr, 1, 0, 0);
    ...
    row = (CvMat*)cvReshapeND(mat, &row_header, 0, 1, 0);
```
Parameters:

arr - Input array

sizeof_header - Size of output header to distinguish between IplImage, CvMat and CvMatND output headers

header - Output header to be filled

new_cn - New number of channels. new_cn = 0 means that the number of channels remains unchanged.

new_dims - New number of dimensions. new_dims = 0 means that the number of dimensions remains the same.

new_sizes - Array of new dimension sizes. Only new_dims-1 values are used, because the total number of elements must remain the same. Thus, if new_dims = 1, new_sizes array is not used.

                              int new_rows)
```
\brief Changes shape of matrix/image without copying data.
The function initializes the CvMat header so that it points to the same data as the original array but has a different shape - different number of channels, different number of rows, or both.
The following example code creates one image buffer and two image headers, the first is for a 320x240x3 image and the second is for a 960x240x1 image:
```
    IplImage* color_img = cvCreateImage(cvSize(320,240), IPL_DEPTH_8U, 3);
    CvMat gray_mat_hdr;
    IplImage gray_img_hdr, *gray_img;
    cvReshape(color_img, &gray_mat_hdr, 1);
    gray_img = cvGetImage(&gray_mat_hdr, &gray_img_hdr);
```
And the next example converts a 3x3 matrix to a single 1x9 vector:
```
    CvMat* mat = cvCreateMat(3, 3, CV_32F);
    CvMat row_header, *row;
    row = cvReshape(mat, &row_header, 0, 1);
```
Parameters:

arr - Input array

header - Output header to be filled

new_cn - New number of channels. 'new_cn = 0' means that the number of channels remains unchanged.

new_rows - New number of rows. 'new_rows = 0' means that the number of rows remains unchanged unless it needs to be changed according to new_cn value.

\brief Allocates array data
The function allocates image, matrix or multi-dimensional dense array data. Note that in the case of matrix types OpenCV allocation functions are used.

                                CvSize roi_size)

\brief Retrieves low-level information about the array.

The function fills output variables with low-level information about the array data. All output

parameters are optional, so some of the pointers may be set to NULL. If the array is IplImage with ROI set, the parameters of ROI are returned.

The following example shows how to get access to array elements. It computes absolute values of the array elements :


    float* data;
    int step;
    CvSize size;

    cvGetRawData(array, (uchar**)&data, &step, &size);
    step /= sizeof(data[0]);

    for(int y = 0; y < size.height; y++, data += step )
        for(int x = 0; x < size.width; x++ )
            data[x] = (float)fabs(data[x]);

Parameters:: arr - Array header; data - Output pointer to the whole image origin or ROI origin if ROI is set; step - Output full row length in bytes; roi_size - Output ROI size

```
\brief Converts one array to another with optional linear transformation.
The function has several different purposes, and thus has several different names. It copies one array to another with optional scaling, which is performed first, and/or optional type conversion, performed after:
```
 \[\texttt{dst} (I) =  \texttt{scale} \texttt{src} (I) + ( \texttt{shift} _0, \texttt{shift} _1,...)\]
```
All the channels of multi-channel arrays are processed independently.
The type of conversion is done with rounding and saturation, that is if the result of scaling + conversion can not be represented exactly by a value of the destination array element type, it is set to the nearest representable value on the real axis.
Parameters:

src - Source array

dst - Destination array

scale - Scale factor

shift - Value added to the scaled source array elements

\brief Calculates the dot product of two arrays in Euclidean metrics.
The function calculates and returns the Euclidean dot product of two arrays.
```
 \[src1  \bullet src2 =  \sum _I ( \texttt{src1} (I)  \texttt{src2} (I))\]
```
In the case of multiple channel arrays, the results for all channels are accumulated. In particular, cvDotProduct(a,a) where a is a complex vector, will return ||\texttt{a}||^2. The function can process multi-dimensional arrays, row by row, layer by layer, and so on.
Parameters:

src1 - The first source array

src2 - The second source array

\brief Fills an array with random numbers and updates the RNG state.
The function fills the destination array with uniformly or normally distributed random numbers.

Parameters:

rng - CvRNG state initialized by cvRNG

arr - The destination array

dist_type - Distribution type > - **CV_RAND_UNI** uniform distribution > - **CV_RAND_NORMAL** normal or Gaussian distribution

param1 - The first parameter of the distribution. In the case of a uniform distribution it is the inclusive lower boundary of the random numbers range. In the case of a normal distribution it is the mean value of the random numbers.

param2 - The second parameter of the distribution. In the case of a uniform distribution it is the exclusive upper boundary of the random numbers range. In the case of a normal distribution it is the standard deviation of the random numbers.

```
\brief Makes OpenCV use IPL functions for allocating IplImage and IplROI structures.
Normally, the function is not called directly. Instead, a simple macro CV_TURN_ON_IPL_COMPATIBILITY() is used that calls cvSetIPLAllocators and passes there pointers to IPL allocation functions. :
```
    ...
    CV_TURN_ON_IPL_COMPATIBILITY()
    ...
```
Parameters:

create_header - pointer to a function, creating IPL image header.

allocate_data - pointer to a function, allocating IPL image data.

deallocate - pointer to a function, deallocating IPL image.

create_roi - pointer to a function, creating IPL image ROI (i.e. Region of Interest).

clone_image - pointer to a function, cloning an IPL image.

\brief Makes a clone of an object.
The function finds the type of a given object and calls clone with the passed object. Of course, if you know the object type, for example, struct_ptr is CvMat\*, it is faster to call the specific function, like cvCloneMat.

Parameters:

struct_ptr - The object to clone

/** \brief Computes the source location of an extrapolated pixel.
The function computes and returns the coordinate of a donor pixel corresponding to the specified extrapolated pixel when using the specified extrapolation border mode. For example, if you use cv::BORDER_WRAP mode in the horizontal direction, cv::BORDER_REFLECT_101 in the vertical direction and want to compute value of the "virtual" pixel Point(-5, 100) in a floating-point image img , it looks like:
```
 {.cpp}
    float val = img.at<float>(borderInterpolate(100, img.rows, cv::BORDER_REFLECT_101),
                              borderInterpolate(-5, img.cols, cv::BORDER_WRAP));
```
Normally, the function is not called directly. It is used inside filtering functions and also in copyMakeBorder.
Parameters:

p - 0-based coordinate of the extrapolated pixel along one of the axes, likely \<0 or \>= len

len - Length of the array along the corresponding axis.

borderType - Border type, one of the #BorderTypes, except for #BORDER_TRANSPARENT and #BORDER_ISOLATED . When borderType==#BORDER_CONSTANT , the function always returns -1, regardless of p and len.

\brief Forms a border around an image.

The function copies the source image into the middle of the destination image. The areas to the left, to the right, above and below the copied source image will be filled with extrapolated pixels. This is not what filtering functions based on it do (they extrapolate pixels on-fly), but what other more complex functions, including your own, may do to simplify image boundary handling.

The function supports the mode when src is already in the middle of dst . In this case, the function does not copy src itself but simply constructs the border, for example:

 {.cpp}
    // let border be the same in all directions
    int border=2;
    // constructs a larger image to fit both the image and the border
    Mat gray_buf(rgb.rows + border*2, rgb.cols + border*2, rgb.depth());
    // select the middle part of it w/o copying data
    Mat gray(gray_canvas, Rect(border, border, rgb.cols, rgb.rows));
    // convert image from RGB to grayscale
    cvtColor(rgb, gray, COLOR_RGB2GRAY);
    // form a border in-place
    copyMakeBorder(gray, gray_buf, border, border,
                   border, border, BORDER_REPLICATE);
    // now do some custom filtering ...
    ...

\note When the source image is a part (ROI) of a bigger image, the function will try to use the pixels outside of the ROI to form a border. To disable this feature and always do extrapolation, as if src was not a ROI, use borderType | #BORDER_ISOLATED.

Parameters:: src - Source image.; dst - Destination image of the same type as src and the size Size(src.cols+left+right, src.rows+top+bottom) .; top - the top pixels; bottom - the bottom pixels; left - the left pixels; right - Parameter specifying how many pixels in each direction from the source image rectangle to extrapolate. For example, top=1, bottom=1, left=1, right=1 mean that 1 pixel-wide border needs to be built.; borderType - Border type. See borderInterpolate for details.; value - Border value if borderType==BORDER_CONSTANT .

\brief Calculates the per-element sum of two arrays or an array and a scalar.
The function add calculates: - Sum of two arrays when both input arrays have the same size and the same number of channels:
```
 \[\texttt{dst}(I) =  \texttt{saturate} ( \texttt{src1}(I) +  \texttt{src2}(I)) \quad \texttt{if mask}(I) \ne0\]
```
- Sum of an array and a scalar when src2 is constructed from Scalar or has the same number of elements as src1.channels():
```
 \[\texttt{dst}(I) =  \texttt{saturate} ( \texttt{src1}(I) +  \texttt{src2} ) \quad \texttt{if mask}(I) \ne0\]
```
- Sum of a scalar and an array when src1 is constructed from Scalar or has the same number of elements as src2.channels():
```
 \[\texttt{dst}(I) =  \texttt{saturate} ( \texttt{src1} +  \texttt{src2}(I) ) \quad \texttt{if mask}(I) \ne0\]
```
where I is a multi-dimensional index of array elements. In case of multi-channel arrays, each channel is processed independently.
The first function in the list above can be replaced with matrix expressions:
```
 {.cpp}
    dst = src1 + src2;
    dst += src1; // equivalent to add(dst, src1, dst);
```
The input arrays and the output array can all have the same or different depths. For example, you can add a 16-bit unsigned array to a 8-bit signed array and store the sum as a 32-bit floating-point array. Depth of the output array is determined by the dtype parameter. In the second and third cases above, as well as in the first case, when src1.depth() == src2.depth(), dtype can be set to the default -1. In this case, the output array will have the same depth as the input array, be it src1, src2 or both. \note Saturation is not applied when the output array has the depth CV_32S. You may even get result of an incorrect sign in the case of overflow.
Parameters:

src1 - first input array or a scalar.

src2 - second input array or a scalar.

dst - output array that has the same size and number of channels as the input array(s); the depth is defined by dtype or src1/src2.

mask - optional operation mask - 8-bit single channel array, that specifies elements of the output array to be changed.

dtype - optional depth of the output array (see the discussion below).

 \[\texttt{dst}(I) =  \texttt{saturate} ( \texttt{src1} -  \texttt{src2}(I) ) \quad \texttt{if mask}(I) \ne0\]
```
- The reverse difference between a scalar and an array in the case of SubRS:
```
 \[\texttt{dst}(I) =  \texttt{saturate} ( \texttt{src2} -  \texttt{src1}(I) ) \quad \texttt{if mask}(I) \ne0\]
```
where I is a multi-dimensional index of array elements. In case of multi-channel arrays, each channel is processed independently.
The first function in the list above can be replaced with matrix expressions:
```
 {.cpp}
    dst = src1 - src2;
    dst -= src1; // equivalent to subtract(dst, src1, dst);
```
The input arrays and the output array can all have the same or different depths. For example, you can subtract to 8-bit unsigned arrays and store the difference in a 16-bit signed array. Depth of the output array is determined by dtype parameter. In the second and third cases above, as well as in the first case, when src1.depth() == src2.depth(), dtype can be set to the default -1. In this case the output array will have the same depth as the input array, be it src1, src2 or both. \note Saturation is not applied when the output array has the depth CV_32S. You may even get result of an incorrect sign in the case of overflow.
Parameters:

src1 - first input array or a scalar.

src2 - second input array or a scalar.

dst - output array of the same size and the same number of channels as the input array.

mask - optional operation mask; this is an 8-bit single channel array that specifies elements of the output array to be changed.

dtype - optional depth of the output array

\brief Calculates the per-element scaled product of two arrays.

The function multiply calculates the per-element product of two arrays:

 \[\texttt{dst} (I)= \texttt{saturate} ( \texttt{scale} \cdot \texttt{src1} (I)  \cdot \texttt{src2} (I))\]

There is also a \ref MatrixExpressions -friendly variant of the first function. See Mat::mul .

For a not-per-element matrix product, see gemm .

\note Saturation is not applied when the output array has the depth CV_32S. You may even get result of an incorrect sign in the case of overflow.

Parameters:: src1 - first input array.; src2 - second input array of the same size and the same type as src1.; dst - output array of the same size and type as src1.; scale - optional scale factor.; dtype - optional depth of the output array

\brief Performs per-element division of two arrays or a scalar by an array.
The function cv::divide divides one array by another:
```
 \[\texttt{dst(I) = saturate(src1(I)*scale/src2(I))}\]
```
or a scalar by an array when there is no src1 :
```
 \[\texttt{dst(I) = saturate(scale/src2(I))}\]
```
Different channels of multi-channel arrays are processed independently.
For integer types when src2(I) is zero, dst(I) will also be zero.
\note In case of floating point data there is no special defined behavior for zero src2(I) values. Regular floating-point division is used. Expect correct IEEE-754 behaviour for floating-point data (with NaN, Inf result values).
\note Saturation is not applied when the output array has the depth CV_32S. You may even get result of an incorrect sign in the case of overflow.
Parameters:

src1 - first input array.

src2 - second input array of the same size and type as src1.

scale - scalar factor.

dst - output array of the same size and type as src2.

dtype - optional depth of the output array; if -1, dst will have depth src2.depth(), but in case of an array-by-array division, you can only pass -1 when src1.depth()==src2.depth().

\brief Calculates the sum of a scaled array and another array.

The function scaleAdd is one of the classical primitive linear algebra operations, known as DAXPY or SAXPY in [BLAS](http://en.wikipedia.org/wiki/Basic_Linear_Algebra_Subprograms). It calculates the sum of a scaled array and another array:

 \[\texttt{dst} (I)= \texttt{scale} \cdot \texttt{src1} (I) +  \texttt{src2} (I)\]

The function can also be emulated with a matrix expression, for example:

 {.cpp}
    Mat A(3, 3, CV_64F);
    ...
    A.row(0) = A.row(1)*2 + A.row(2);

Parameters:: src1 - first input array.; alpha - scale factor for the first array.; src2 - second input array of the same size and type as src1.; dst - output array of the same size and type as src1.

\brief Calculates the weighted sum of two arrays.

The function addWeighted calculates the weighted sum of two arrays as follows:

 \[\texttt{dst} (I)= \texttt{saturate} ( \texttt{src1} (I)* \texttt{alpha} +  \texttt{src2} (I)* \texttt{beta} +  \texttt{gamma} )\]

where I is a multi-dimensional index of array elements. In case of multi-channel arrays, each channel is processed independently. The function can be replaced with a matrix expression:

 {.cpp}
    dst = src1*alpha + src2*beta + gamma;

\note Saturation is not applied when the output array has the depth CV_32S. You may even get result of an incorrect sign in the case of overflow.

Parameters:: src1 - first input array.; alpha - weight of the first array elements.; src2 - second input array of the same size and channel number as src1.; beta - weight of the second array elements.; gamma - scalar added to each sum.; dst - output array that has the same size and number of channels as the input arrays.; dtype - optional depth of the output array; when both input arrays have the same depth, dtype can be set to -1, which will be equivalent to src1.depth().

\brief Scales, calculates absolute values, and converts the result to 8-bit.

On each element of the input array, the function convertScaleAbs performs three operations sequentially: scaling, taking an absolute value, conversion to an unsigned 8-bit type:

 \[\texttt{dst} (I)= \texttt{saturate\_cast<uchar>} (| \texttt{src} (I)* \texttt{alpha} +  \texttt{beta} |)\]

In case of multi-channel arrays, the function processes each channel independently. When the output is not 8-bit, the operation can be emulated by calling the Mat::convertTo method (or by using matrix expressions) and then by calculating an absolute value of the result. For example:

 {.cpp}
    Mat_<float> A(30,30);
    randu(A, Scalar(-100), Scalar(100));
    Mat_<float> B = A*5 + 3;
    B = abs(B);
    // Mat_<float> B = abs(A*5+3) will also do the job,
    // but it will allocate a temporary matrix

Parameters:: src - input array.; dst - output array.; alpha - optional scale factor.; beta - optional delta added to the scaled values.

\brief Converts an array to half precision floating number.
This function converts FP32 (single precision floating point) from/to FP16 (half precision floating point). CV_16S format is used to represent FP16 data. There are two use modes (src -> dst): CV_32F -> CV_16S and CV_16S -> CV_32F. The input array has to have type of CV_32F or CV_16S to represent the bit depth. If the input array is neither of them, the function will raise an error. The format of half precision floating point is defined in IEEE 754-2008.

Parameters:

src - input array.

dst - output array.

\brief Performs a look-up table transform of an array.

The function LUT fills the output array with values from the look-up table. Indices of the entries are taken from the input array. That is, the function processes each element of src as follows:

 \[\texttt{dst} (I)  \leftarrow \texttt{lut(src(I) + d)}\]

where

 \[d =  \fork{0}{if \(\texttt{src}\) has depth \(\texttt{CV_8U}\)}{128}{if \(\texttt{src}\) has depth \(\texttt{CV_8S}\)}\]

Parameters:: src - input array of 8-bit elements.; lut - look-up table of 256 elements; in case of multi-channel input array, the table should either have a single channel (in this case the same table is used for all channels) or the same number of channels as in the input array.; dst - output array of the same size and number of channels as src, and the same depth as lut.

Calculates a mean and standard deviation of array elements.

The function cv::meanStdDev calculates the mean and the standard deviation M of array elements independently for each channel and returns it via the output parameters:

 \[\begin{array}{l} N =  \sum _{I, \texttt{mask} (I)  \ne 0} 1 \\ \texttt{mean} _c =  \frac{\sum_{ I: \; \texttt{mask}(I) \ne 0} \texttt{src} (I)_c}{N} \\ \texttt{stddev} _c =  \sqrt{\frac{\sum_{ I: \; \texttt{mask}(I) \ne 0} \left ( \texttt{src} (I)_c -  \texttt{mean} _c \right )^2}{N}} \end{array}\]

When all the mask elements are 0's, the function returns mean=stddev=Scalar::all(0). \note The calculated standard deviation is only the diagonal of the complete normalized covariance matrix. If the full matrix is needed, you can reshape the multi-channel array M x N to the single-channel array M\*N x mtx.channels() (only possible when the matrix is continuous) and then pass the matrix to calcCovarMatrix .

Parameters:: src - input array that should have from 1 to 4 channels so that the results can be stored in Scalar_ 's.; mean - output parameter: calculated mean value.; stddev - output parameter: calculated standard deviation.; mask - optional operation mask.

\brief Calculates the absolute norm of an array.
This version of #norm calculates the absolute norm of src1. The type of norm to calculate is specified using #NormTypes.
As example for one array consider the function r(x)= \begin{pmatrix} x \\ 1-x \end{pmatrix}, x \in [-1;1]. The L_{1}, L_{2} and L_{\infty} norm for the sample value r(-1) = \begin{pmatrix} -1 \\ 2 \end{pmatrix} is calculated as follows \f{align*} \| r(-1) \|_{L_1} &= |-1| + |2| = 3 \ \| r(-1) \|_{L_2} &= \sqrt{(-1)^{2} + (2)^{2}} = \sqrt{5} \ \| r(-1) \|_{L_\infty} &= \max(|-1|,|2|) = 2 \f} and for r(0.5) = \begin{pmatrix} 0.5 \\ 0.5 \end{pmatrix} the calculation is \f{align*} \| r(0.5) \|_{L_1} &= |0.5| + |0.5| = 1 \ \| r(0.5) \|_{L_2} &= \sqrt{(0.5)^{2} + (0.5)^{2}} = \sqrt{0.5} \ \| r(0.5) \|_{L_\infty} &= \max(|0.5|,|0.5|) = 0.5. \f} The following graphic shows all values for the three norm functions \| r(x) \|_{L_1}, \| r(x) \|_{L_2} and \| r(x) \|_{L_\infty}. It is notable that the L_{1} norm forms the upper and the L_{\infty} norm forms the lower border for the example function r(x) . ![Graphs for the different norm functions from the above example](pics/NormTypes_OneArray_1-2-INF.png)
When the mask parameter is specified and it is not empty, the norm is
If normType is not specified, #NORM_L2 is used. calculated only over the region specified by the mask.
Multi-channel input arrays are treated as single-channel arrays, that is, the results for all channels are combined.
Hamming norms can only be calculated with CV_8U depth arrays.

Parameters:

src1 - first input array.

normType - type of the norm (see #NormTypes).

mask - optional operation mask; it must have the same size as src1 and CV_8UC1 type.

\brief Computes the Peak Signal-to-Noise Ratio (PSNR) image quality metric.
This function calculates the Peak Signal-to-Noise Ratio (PSNR) image quality metric in decibels (dB), between two input arrays src1 and src2. The arrays must have the same type.
The PSNR is calculated as follows:
```
 \[
\texttt{PSNR} = 10 \cdot \log_{10}{\left( \frac{R^2}{MSE} \right) }
\]
```
where R is the maximum integer value of depth (e.g. 255 in the case of CV_8U data) and MSE is the mean squared error between the two arrays.
Parameters:

src1 - first input array.

src2 - second input array of the same size as src1.

R - the maximum pixel value (255 by default)

\brief Normalizes the norm or value range of an array.

The function cv::normalize normalizes scale and shift the input array elements so that

 \[\| \texttt{dst} \| _{L_p}= \texttt{alpha}\]

(where p=Inf, 1 or 2) when normType=NORM_INF, NORM_L1, or NORM_L2, respectively; or so that

 \[\min _I  \texttt{dst} (I)= \texttt{alpha} , \, \, \max _I  \texttt{dst} (I)= \texttt{beta}\]

when normType=NORM_MINMAX (for dense arrays only). The optional mask specifies a sub-array to be normalized. This means that the norm or min-n-max are calculated over the sub-array, and then this sub-array is modified to be normalized. If you want to only use the mask to calculate the norm or min-max but modify the whole array, you can use norm and Mat::convertTo.

In case of sparse matrices, only the non-zero values are analyzed and transformed. Because of this, the range transformation for sparse matrices is not allowed since it can shift the zero level.

Possible usage with some positive example data:

 {.cpp}
    vector<double> positiveData = { 2.0, 8.0, 10.0 };
    vector<double> normalizedData_l1, normalizedData_l2, normalizedData_inf, normalizedData_minmax;

    // Norm to probability (total count)
    // sum(numbers) = 20.0
    // 2.0      0.1     (2.0/20.0)
    // 8.0      0.4     (8.0/20.0)
    // 10.0     0.5     (10.0/20.0)
    normalize(positiveData, normalizedData_l1, 1.0, 0.0, NORM_L1);

    // Norm to unit vector: ||positiveData|| = 1.0
    // 2.0      0.15
    // 8.0      0.62
    // 10.0     0.77
    normalize(positiveData, normalizedData_l2, 1.0, 0.0, NORM_L2);

    // Norm to max element
    // 2.0      0.2     (2.0/10.0)
    // 8.0      0.8     (8.0/10.0)
    // 10.0     1.0     (10.0/10.0)
    normalize(positiveData, normalizedData_inf, 1.0, 0.0, NORM_INF);

    // Norm to range [0.0;1.0]
    // 2.0      0.0     (shift to left border)
    // 8.0      0.75    (6.0/8.0)
    // 10.0     1.0     (shift to right border)
    normalize(positiveData, normalizedData_minmax, 1.0, 0.0, NORM_MINMAX);

Parameters:: src - input array.; dst - output array of the same size as src .; alpha - norm value to normalize to or the lower range boundary in case of the range normalization.; beta - upper range boundary in case of the range normalization; it is not used for the norm normalization.; norm_type - normalization type (see cv::NormTypes).; dtype - when negative, the output array has the same type as src; otherwise, it has the same number of channels as src and the depth =CV_MAT_DEPTH(dtype).; mask - optional operation mask.

\brief Finds the global minimum and maximum in an array.
The function cv::minMaxLoc finds the minimum and maximum element values and their positions. The extremums are searched across the whole array or, if mask is not an empty array, in the specified array region.
The function do not work with multi-channel arrays. If you need to find minimum or maximum elements across all the channels, use Mat::reshape first to reinterpret the array as single-channel. Or you may extract the particular channel using either extractImageCOI , or mixChannels , or split .

Parameters:

src - input single-channel array.

minVal - pointer to the returned minimum value; NULL is used if not required.

maxVal - pointer to the returned maximum value; NULL is used if not required.

minLoc - pointer to the returned minimum location (in 2D case); NULL is used if not required.

maxLoc - pointer to the returned maximum location (in 2D case); NULL is used if not required.

mask - optional mask used to select a sub-array.

\brief Finds the global minimum and maximum in an array
The function cv::minMaxIdx finds the minimum and maximum element values and their positions. The extremums are searched across the whole array or, if mask is not an empty array, in the specified array region. The function does not work with multi-channel arrays. If you need to find minimum or maximum elements across all the channels, use Mat::reshape first to reinterpret the array as single-channel. Or you may extract the particular channel using either extractImageCOI , or mixChannels , or split . In case of a sparse matrix, the minimum is found among non-zero elements only. \note When minIdx is not NULL, it must have at least 2 elements (as well as maxIdx), even if src is a single-row or single-column matrix. In OpenCV (following MATLAB) each array has at least 2 dimensions, i.e. single-column matrix is Mx1 matrix (and therefore minIdx/maxIdx will be (i1,0)/(i2,0)) and single-row matrix is 1xN matrix (and therefore minIdx/maxIdx will be (0,j1)/(0,j2)).

Parameters:

src - input single-channel array.

minVal - pointer to the returned minimum value; NULL is used if not required.

maxVal - pointer to the returned maximum value; NULL is used if not required.

minIdx - pointer to the returned minimum location (in nD case); NULL is used if not required; Otherwise, it must point to an array of src.dims elements, the coordinates of the minimum element in each dimension are stored there sequentially.

maxIdx - pointer to the returned maximum location (in nD case). NULL is used if not required.

mask - specified array region

\brief Reduces a matrix to a vector.
The function #reduce reduces the matrix to a vector by treating the matrix rows/columns as a set of 1D vectors and performing the specified operation on the vectors until a single row/column is obtained. For example, the function can be used to compute horizontal and vertical projections of a raster image. In case of #REDUCE_MAX and #REDUCE_MIN , the output image should have the same type as the source one. In case of #REDUCE_SUM and #REDUCE_AVG , the output may have a larger element bit-depth to preserve accuracy. And multi-channel arrays are also supported in these two reduction modes.
The following code demonstrates its usage for a single channel matrix. \snippet snippets/core_reduce.cpp example
And the following code demonstrates its usage for a two-channel matrix. \snippet snippets/core_reduce.cpp example2

Parameters:

src - input 2D matrix.

dst - output vector. Its size and type is defined by dim and dtype parameters.

dim - dimension index along which the matrix is reduced. 0 means that the matrix is reduced to a single row. 1 means that the matrix is reduced to a single column.

rtype - reduction operation that could be one of #ReduceTypes

dtype - when negative, the output vector will have the same type as the input matrix, otherwise, its type will be CV_MAKE_TYPE(CV_MAT_DEPTH(dtype), src.channels()).

\brief Creates one multi-channel array out of several single-channel ones.
The function cv::merge merges several arrays to make a single multi-channel array. That is, each element of the output array will be a concatenation of the elements of the input arrays, where elements of i-th input array are treated as mv[i].channels()-element vectors.
The function cv::split does the reverse operation. If you need to shuffle channels in some other advanced way, use cv::mixChannels.
The following example shows how to merge 3 single channel matrices into a single 3-channel matrix. \snippet snippets/core_merge.cpp example

Parameters:

mv - input array of matrices to be merged; all the matrices in mv must have the same size and the same depth.

count - number of input matrices when mv is a plain C array; it must be greater than zero.

dst - output array of the same size and the same depth as mv[0]; The number of channels will be equal to the parameter count.

\brief Divides a multi-channel array into several single-channel arrays.
The function cv::split splits a multi-channel array into separate single-channel arrays:
```
 \[\texttt{mv} [c](I) =  \texttt{src} (I)_c\]
```
If you need to extract a single channel or do some other sophisticated channel permutation, use mixChannels .
The following example demonstrates how to split a 3-channel matrix into 3 single channel matrices. \snippet snippets/core_split.cpp example
Parameters:

src - input multi-channel array.

mvbegin - output array; the number of arrays must match src.channels(); the arrays themselves are reallocated, if needed.

\brief Copies specified channels from input arrays to the specified channels of output arrays.
The function cv::mixChannels provides an advanced mechanism for shuffling image channels.
cv::split,cv::merge,cv::extractChannel,cv::insertChannel and some forms of cv::cvtColor are partial cases of cv::mixChannels.
In the example below, the code splits a 4-channel BGRA image into a 3-channel BGR (with B and R channels swapped) and a separate alpha-channel image:
```
 {.cpp}
    Mat bgra( 100, 100, CV_8UC4, Scalar(255,0,0,255) );
    Mat bgr( bgra.rows, bgra.cols, CV_8UC3 );
    Mat alpha( bgra.rows, bgra.cols, CV_8UC1 );

    // forming an array of matrices is a quite efficient operation,
    // because the matrix data is not copied, only the headers
    Mat out[] = { bgr, alpha };
    // bgra[0] -> bgr[2], bgra[1] -> bgr[1],
    // bgra[2] -> bgr[0], bgra[3] -> alpha[0]
    int from_to[] = { 0,2, 1,1, 2,0, 3,3 };
    mixChannels( &bgra, 1, out, 2, from_to, 4 );
```
\note Unlike many other new-style C++ functions in OpenCV (see the introduction section and Mat::create ), cv::mixChannels requires the output arrays to be pre-allocated before calling the function.
Parameters:

src - input array or vector of matrices; all of the matrices must have the same size and the same depth.

nsrcs - number of matrices in src.

dst - output array or vector of matrices; all the matrices **must be allocated**; their size and depth must be the same as in src[0].

ndsts - number of matrices in dst.

fromTo - array of index pairs specifying which channels are copied and where; fromTo[k\*2] is a 0-based index of the input channel in src, fromTo[k\*2+1] is an index of the output channel in dst; the continuous channel numbering is used: the first input image channels are indexed from 0 to src[0].channels()-1, the second input image channels are indexed from src[0].channels() to src[0].channels() + src[1].channels()-1, and so on, the same scheme is used for the output image channels; as a special case, when fromTo[k\*2] is negative, the corresponding output channel is filled with zero .

npairs - number of index pairs in fromTo.

```
\brief Flips a 2D array around vertical, horizontal, or both axes.
The function cv::flip flips the array in one of three different ways (row and column indices are 0-based):
```
 \[\texttt{dst} _{ij} =
\left\{
\begin{array}{l l}
\texttt{src} _{\texttt{src.rows}-i-1,j} & if\;  \texttt{flipCode} = 0 \\
\texttt{src} _{i, \texttt{src.cols} -j-1} & if\;  \texttt{flipCode} > 0 \\
\texttt{src} _{ \texttt{src.rows} -i-1, \texttt{src.cols} -j-1} & if\; \texttt{flipCode} < 0 \\
\end{array}
\right.\]}
```
The example scenarios of using the function are the following: Vertical flipping of the image (flipCode == 0) to switch between top-left and bottom-left image origin. This is a typical operation in video processing on Microsoft Windows\* OS. Horizontal flipping of the image with the subsequent horizontal shift and absolute difference calculation to check for a vertical-axis symmetry (flipCode \> 0). Simultaneous horizontal and vertical flipping of the image with the subsequent shift and absolute difference calculation to check for a central symmetry (flipCode \< 0). Reversing the order of point arrays (flipCode \> 0 or flipCode == 0).
Parameters:

src - input array.

dst - output array of the same size and type as src.

flipCode - a flag to specify how to flip the array; 0 means flipping around the x-axis and positive value (for example, 1) means flipping around y-axis. Negative value (for example, -1) means flipping around both axes.

\brief Rotates a 2D array in multiples of 90 degrees. The function cv::rotate rotates the array in one of three different ways: Rotate by 90 degrees clockwise (rotateCode = ROTATE_90_CLOCKWISE). Rotate by 180 degrees clockwise (rotateCode = ROTATE_180). Rotate by 270 degrees clockwise (rotateCode = ROTATE_90_COUNTERCLOCKWISE).

Parameters:

src - input array.

dst - output array of the same type as src. The size is the same with ROTATE_180, and the rows and cols are switched for ROTATE_90_CLOCKWISE and ROTATE_90_COUNTERCLOCKWISE.

rotateCode - an enum to specify how to rotate the array; see the enum #RotateFlags

\brief Fills the output array with repeated copies of the input array.

The function cv::repeat duplicates the input array one or more times along each of the two axes:

 \[\texttt{dst} _{ij}= \texttt{src} _{i\mod src.rows, \; j\mod src.cols }\]

The second variant of the function is more convenient to use with \ref MatrixExpressions.

Parameters:: src - input array to replicate.; ny - Flag to specify how many times the src is repeated along the vertical axis.; nx - Flag to specify how many times the src is repeated along the horizontal axis.; dst - output array of the same type as src.

\brief computes bitwise conjunction of the two arrays (dst = src1 & src2) Calculates the per-element bit-wise conjunction of two arrays or an array and a scalar.

The function cv::bitwise_and calculates the per-element bit-wise logical conjunction for: Two arrays when src1 and src2 have the same size:

 \[\texttt{dst} (I) =  \texttt{src1} (I)  \wedge \texttt{src2} (I) \quad \texttt{if mask} (I) \ne0\]

An array and a scalar when src2 is constructed from Scalar or has the same number of elements as src1.channels():

 \[\texttt{dst} (I) =  \texttt{src1} (I)  \wedge \texttt{src2} \quad \texttt{if mask} (I) \ne0\]

A scalar and an array when src1 is constructed from Scalar or has the same number of elements as src2.channels():

 \[\texttt{dst} (I) =  \texttt{src1}  \wedge \texttt{src2} (I) \quad \texttt{if mask} (I) \ne0\]

In case of floating-point arrays, their machine-specific bit representations (usually IEEE754-compliant) are used for the operation. In case of multi-channel arrays, each channel is processed independently. In the second and third cases above, the scalar is first converted to the array type.

Parameters:: src1 - first input array or a scalar.; src2 - second input array or a scalar.; dst - output array that has the same size and type as the input arrays.; mask - optional operation mask, 8-bit single channel array, that specifies elements of the output array to be changed.

\brief Calculates the per-element bit-wise "exclusive or" operation on two arrays or an array and a scalar.

The function cv::bitwise_xor calculates the per-element bit-wise logical "exclusive-or" operation for: Two arrays when src1 and src2 have the same size:

 \[\texttt{dst} (I) =  \texttt{src1} (I)  \oplus \texttt{src2} (I) \quad \texttt{if mask} (I) \ne0\]

An array and a scalar when src2 is constructed from Scalar or has the same number of elements as src1.channels():

 \[\texttt{dst} (I) =  \texttt{src1} (I)  \oplus \texttt{src2} \quad \texttt{if mask} (I) \ne0\]

A scalar and an array when src1 is constructed from Scalar or has the same number of elements as src2.channels():

 \[\texttt{dst} (I) =  \texttt{src1}  \oplus \texttt{src2} (I) \quad \texttt{if mask} (I) \ne0\]

In case of floating-point arrays, their machine-specific bit representations (usually IEEE754-compliant) are used for the operation. In case of multi-channel arrays, each channel is processed independently. In the 2nd and 3rd cases above, the scalar is first converted to the array type.

Parameters:: src1 - first input array or a scalar.; src2 - second input array or a scalar.; dst - output array that has the same size and type as the input arrays.; mask - optional operation mask, 8-bit single channel array, that specifies elements of the output array to be changed.

\brief Inverts every bit of an array.

The function cv::bitwise_not calculates per-element bit-wise inversion of the input array:

 \[\texttt{dst} (I) =  \neg \texttt{src} (I)\]

In case of a floating-point input array, its machine-specific bit representation (usually IEEE754-compliant) is used for the operation. In case of multi-channel arrays, each channel is processed independently.

Parameters:: src - input array.; dst - output array that has the same size and type as the input array.; mask - optional operation mask, 8-bit single channel array, that specifies elements of the output array to be changed.

\brief Calculates the per-element absolute difference between two arrays or between an array and a scalar.
The function cv::absdiff calculates: Absolute difference between two arrays when they have the same size and type:
```
 \[\texttt{dst}(I) =  \texttt{saturate} (| \texttt{src1}(I) -  \texttt{src2}(I)|)\]
```
Absolute difference between an array and a scalar when the second array is constructed from Scalar or has as many elements as the number of channels in src1:
```
 \[\texttt{dst}(I) =  \texttt{saturate} (| \texttt{src1}(I) -  \texttt{src2} |)\]
```
Absolute difference between a scalar and an array when the first array is constructed from Scalar or has as many elements as the number of channels in src2:
```
 \[\texttt{dst}(I) =  \texttt{saturate} (| \texttt{src1} -  \texttt{src2}(I) |)\]
```
where I is a multi-dimensional index of array elements. In case of multi-channel arrays, each channel is processed independently. \note Saturation is not applied when the arrays have the depth CV_32S. You may even get a negative value in the case of overflow.
Parameters:

src1 - first input array or a scalar.

src2 - second input array or a scalar.

dst - output array that has the same size and type as input arrays.

\brief This is an overloaded member function, provided for convenience (python) Copies the matrix to another one. When the operation mask is specified, if the Mat::create call shown above reallocates the matrix, the newly allocated matrix is initialized with all zeros before copying the data.

Parameters:

src - source matrix.

dst - Destination matrix. If it does not have a proper size or type before the operation, it is reallocated.

mask - Operation mask of the same size as \*this. Its non-zero elements indicate which matrix elements need to be copied. The mask has to be of type CV_8U and can have 1 or multiple channels.

\brief Checks if array elements lie between the elements of two other arrays.

The function checks the range as follows: - For every element of a single-channel input array:

 \[\texttt{dst} (I)= \texttt{lowerb} (I)_0  \leq \texttt{src} (I)_0 \leq  \texttt{upperb} (I)_0\]

- For two-channel arrays:

 \[\texttt{dst} (I)= \texttt{lowerb} (I)_0  \leq \texttt{src} (I)_0 \leq  \texttt{upperb} (I)_0  \land \texttt{lowerb} (I)_1  \leq \texttt{src} (I)_1 \leq  \texttt{upperb} (I)_1\]

- and so forth.

That is, dst (I) is set to 255 (all 1 -bits) if src (I) is within the specified 1D, 2D, 3D, ... box and 0 otherwise.

When the lower and/or upper boundary parameters are scalars, the indexes (I) at lowerb and upperb in the above formulas should be omitted.

Parameters:: src - first input array.; lowerb - inclusive lower boundary array or a scalar.; upperb - inclusive upper boundary array or a scalar.; dst - output array of the same size as src and CV_8U type.

\brief Performs the per-element comparison of two arrays or an array and scalar value.

The function compares: Elements of two arrays when src1 and src2 have the same size:

 \[\texttt{dst} (I) =  \texttt{src1} (I)  \,\texttt{cmpop}\, \texttt{src2} (I)\]

Elements of src1 with a scalar src2 when src2 is constructed from Scalar or has a single element:

 \[\texttt{dst} (I) =  \texttt{src1}(I) \,\texttt{cmpop}\,  \texttt{src2}\]

src1 with elements of src2 when src1 is constructed from Scalar or has a single element:

 \[\texttt{dst} (I) =  \texttt{src1}  \,\texttt{cmpop}\, \texttt{src2} (I)\]

When the comparison result is true, the corresponding element of output array is set to 255. The comparison operations can be replaced with the equivalent matrix expressions:

 {.cpp}
    Mat dst1 = src1 >= src2;
    Mat dst2 = src1 < 8;
    ...

Parameters:: src1 - first input array or a scalar; when it is an array, it must have a single channel.; src2 - second input array or a scalar; when it is an array, it must have a single channel.; dst - output array of type ref CV_8U that has the same size and the same number of channels as the input arrays.; cmpop - a flag, that specifies correspondence between the arrays (cv::CmpTypes)

\brief Raises every array element to a power.
The function cv::pow raises every element of the input array to power :
```
 \[\texttt{dst} (I) =  \fork{\texttt{src}(I)^{power}}{if \(\texttt{power}\) is integer}{|\texttt{src}(I)|^{power}}{otherwise}\]
```
So, for a non-integer power exponent, the absolute values of input array elements are used. However, it is possible to get true values for negative values using some extra operations. In the example below, computing the 5th root of array src shows:
```
 {.cpp}
    Mat mask = src < 0;
    pow(src, 1./5, dst);
    subtract(Scalar::all(0), dst, dst, mask);
```
For some values of power, such as integer values, 0.5 and -0.5, specialized faster algorithms are used.
Special values (NaN, Inf) are not handled.
Parameters:

src - input array.

power - exponent of power.

dst - output array of the same size and type as src.

\brief Calculates the exponent of every array element.
The function cv::exp calculates the exponent of every element of the input array:
```
 \[\texttt{dst} [I] = e^{ src(I) }\]
```
The maximum relative error is about 7e-6 for single-precision input and less than 1e-10 for double-precision input. Currently, the function converts denormalized values to zeros on output. Special values (NaN, Inf) are not handled.
Parameters:

src - input array.

dst - output array of the same size and type as src.

\brief Calculates x and y coordinates of 2D vectors from their magnitude and angle.

The function cv::polarToCart calculates the Cartesian coordinates of each 2D vector represented by the corresponding elements of magnitude and angle:

 \[\begin{array}{l} \texttt{x} (I) =  \texttt{magnitude} (I) \cos ( \texttt{angle} (I)) \\ \texttt{y} (I) =  \texttt{magnitude} (I) \sin ( \texttt{angle} (I)) \\ \end{array}\]

The relative accuracy of the estimated coordinates is about 1e-6.

Parameters:: magnitude - input floating-point array of magnitudes of 2D vectors; it can be an empty matrix (=Mat()), in this case, the function assumes that all the magnitudes are =1; if it is not empty, it must have the same size and type as angle.; angle - input floating-point array of angles of 2D vectors.; x - output array of x-coordinates of 2D vectors; it has the same size and type as angle.; y - output array of y-coordinates of 2D vectors; it has the same size and type as angle.; angleInDegrees - when true, the input angles are measured in degrees, otherwise, they are measured in radians.

\brief Calculates the magnitude and angle of 2D vectors.

The function cv::cartToPolar calculates either the magnitude, angle, or both for every 2D vector (x(I),y(I)):

 \[\begin{array}{l} \texttt{magnitude} (I)= \sqrt{\texttt{x}(I)^2+\texttt{y}(I)^2} , \\ \texttt{angle} (I)= \texttt{atan2} ( \texttt{y} (I), \texttt{x} (I))[ \cdot180 / \pi ] \end{array}\]

The angles are calculated with accuracy about 0.3 degrees. For the point (0,0), the angle is set to 0.

Parameters:: x - array of x-coordinates; this must be a single-precision or double-precision floating-point array.; y - array of y-coordinates, that must have the same size and same type as x.; magnitude - output array of magnitudes of the same size and type as x.; angle - output array of angles that has the same size and type as x; the angles are measured in radians (from 0 to 2\*Pi) or in degrees (0 to 360 degrees).; angleInDegrees - a flag, indicating whether the angles are measured in radians (which is by default), or in degrees.

\brief Calculates the rotation angle of 2D vectors.

The function cv::phase calculates the rotation angle of each 2D vector that is formed from the corresponding elements of x and y :

 \[\texttt{angle} (I) =  \texttt{atan2} ( \texttt{y} (I), \texttt{x} (I))\]

The angle estimation accuracy is about 0.3 degrees. When x(I)=y(I)=0 , the corresponding angle(I) is set to 0.

Parameters:: x - input floating-point array of x-coordinates of 2D vectors.; y - input array of y-coordinates of 2D vectors; it must have the same size and the same type as x.; angle - output array of vector angles; it has the same size and same type as x .; angleInDegrees - when true, the function calculates the angle in degrees, otherwise, they are measured in radians.

\brief Checks every element of an input array for invalid values.
The function cv::checkRange checks that every array element is neither NaN nor infinite. When minVal \> -DBL_MAX and maxVal \< DBL_MAX, the function also checks that each value is between minVal and maxVal. In case of multi-channel arrays, each channel is processed independently. If some values are out of range, position of the first outlier is stored in pos (when pos != NULL). Then, the function either returns false (when quiet=true) or throws an exception.

Parameters:

a - input array.

quiet - a flag, indicating whether the functions quietly return false when the array elements are out of range or they throw an exception.

pos - optional output parameter, when not NULL, must be a pointer to array of src.dims elements.

minVal - inclusive lower boundary of valid values range.

maxVal - exclusive upper boundary of valid values range.

\brief Performs generalized matrix multiplication.

The function cv::gemm performs generalized matrix multiplication similar to the gemm functions in BLAS level 3. For example, gemm(src1, src2, alpha, src3, beta, dst, GEMM_1_T + GEMM_3_T) corresponds to

 \[\texttt{dst} =  \texttt{alpha} \cdot \texttt{src1} ^T  \cdot \texttt{src2} +  \texttt{beta} \cdot \texttt{src3} ^T\]

In case of complex (two-channel) data, performed a complex matrix multiplication.

The function can be replaced with a matrix expression. For example, the above call can be replaced with:

 {.cpp}
    dst = alpha*src1.t()*src2 + beta*src3.t();

Parameters:: src1 - first multiplied input matrix that could be real(CV_32FC1, CV_64FC1) or complex(CV_32FC2, CV_64FC2).; src2 - second multiplied input matrix of the same type as src1.; alpha - weight of the matrix product.; src3 - third optional delta matrix added to the matrix product; it should have the same type as src1 and src2.; beta - weight of src3.; dst - output matrix; it has the proper size and the same type as input matrices.; flags - operation flags (cv::GemmFlags)

\brief Calculates the product of a matrix and its transposition.
The function cv::mulTransposed calculates the product of src and its transposition:
```
 \[\texttt{dst} = \texttt{scale} ( \texttt{src} - \texttt{delta} )^T ( \texttt{src} - \texttt{delta} )\]
```
if aTa=true , and
```
 \[\texttt{dst} = \texttt{scale} ( \texttt{src} - \texttt{delta} ) ( \texttt{src} - \texttt{delta} )^T\]
```
otherwise. The function is used to calculate the covariance matrix. With zero delta, it can be used as a faster substitute for general matrix product A\*B when B=A'
Parameters:

src - input single-channel matrix. Note that unlike gemm, the function can multiply not only floating-point matrices.

dst - output square matrix.

aTa - Flag specifying the multiplication ordering. See the description below.

delta - Optional delta matrix subtracted from src before the multiplication. When the matrix is empty ( delta=noArray() ), it is assumed to be zero, that is, nothing is subtracted. If it has the same size as src , it is simply subtracted. Otherwise, it is "repeated" (see repeat ) to cover the full src and then subtracted. Type of the delta matrix, when it is not empty, must be the same as the type of created output matrix. See the dtype parameter description below.

scale - Optional scale factor for the matrix product.

dtype - Optional type of the output matrix. When it is negative, the output matrix will have the same type as src . Otherwise, it will be type=CV_MAT_DEPTH(dtype) that should be either CV_32F or CV_64F .

\brief Performs the matrix transformation of every array element.
The function cv::transform performs the matrix transformation of every element of the array src and stores the results in dst :
```
 \[\texttt{dst} (I) =  \texttt{m} \cdot \texttt{src} (I)\]
```
(when m.cols=src.channels() ), or
```
 \[\texttt{dst} (I) =  \texttt{m} \cdot [ \texttt{src} (I); 1]\]
```
(when m.cols=src.channels()+1 )
Every element of the N -channel array src is interpreted as N -element vector that is transformed using the M x N or M x (N+1) matrix m to M-element vector - the corresponding element of the output array dst .
The function may be used for geometrical transformation of N -dimensional points, arbitrary linear color space transformation (such as various kinds of RGB to YUV transforms), shuffling the image channels, and so forth.
Parameters:

src - input array that must have as many channels (1 to 4) as m.cols or m.cols-1.

dst - output array of the same size and depth as src; it has as many channels as m.rows.

m - transformation 2x2 or 2x3 floating-point matrix.

```
\brief Performs the perspective matrix transformation of vectors.
The function cv::perspectiveTransform transforms every element of src by treating it as a 2D or 3D vector, in the following way:
```
 \[(x, y, z)  \rightarrow (x'/w, y'/w, z'/w)\]
```
where
```
 \[(x', y', z', w') =  \texttt{mat} \cdot \begin{bmatrix} x & y & z & 1  \end{bmatrix}\]
```
and
```
 \[w =  \fork{w'}{if \(w' \ne 0\)}{\infty}{otherwise}\]
```
Here a 3D vector transformation is shown. In case of a 2D vector transformation, the z component is omitted.
\note The function transforms a sparse set of 2D or 3D vectors. If you want to transform an image using perspective transformation, use warpPerspective . If you have an inverse problem, that is, you want to compute the most probable perspective transformation out of several pairs of corresponding points, you can use getPerspectiveTransform or findHomography .
Parameters:

src - input two-channel or three-channel floating-point array; each element is a 2D/3D vector to be transformed.

dst - output array of the same size and type as src.

m - 3x3 or 4x4 floating-point transformation matrix.

Parameters:

m - input-output floating-point square matrix.

lowerToUpper - operation flag; if true, the lower half is copied to the upper half. Otherwise, the upper half is copied to the lower half.

\brief Returns the determinant of a square floating-point matrix.
The function cv::determinant calculates and returns the determinant of the specified matrix. For small matrices ( mtx.cols=mtx.rows\<=3 ), the direct method is used. For larger matrices, the function uses LU factorization with partial pivoting.
For symmetric positively-determined matrices, it is also possible to use eigen decomposition to calculate the determinant.

Parameters:

mtx - input matrix that must have CV_32FC1 or CV_64FC1 type and square size.

\brief Finds the inverse or pseudo-inverse of a matrix.
The function cv::invert inverts the matrix src and stores the result in dst . When the matrix src is singular or non-square, the function calculates the pseudo-inverse matrix (the dst matrix) so that norm(src\*dst - I) is minimal, where I is an identity matrix.
In case of the #DECOMP_LU method, the function returns non-zero value if the inverse has been successfully calculated and 0 if src is singular.
In case of the #DECOMP_SVD method, the function returns the inverse condition number of src (the ratio of the smallest singular value to the largest singular value) and 0 if src is singular. The SVD method calculates a pseudo-inverse matrix if src is singular.
Similarly to #DECOMP_LU, the method #DECOMP_CHOLESKY works only with non-singular square matrices that should also be symmetrical and positively defined. In this case, the function stores the inverted matrix in dst and returns non-zero. Otherwise, it returns 0.

Parameters:

src - input floating-point M x N matrix.

dst - output matrix of N x M size and the same type as src.

flags - inversion method (cv::DecompTypes)

\brief Solves one or more linear systems or least-squares problems.

The function cv::solve solves a linear system or least-squares problem (the latter is possible with SVD or QR methods, or by specifying the flag #DECOMP_NORMAL ):

 \[\texttt{dst} =  \arg \min _X \| \texttt{src1} \cdot \texttt{X} -  \texttt{src2} \|\]

If #DECOMP_LU or #DECOMP_CHOLESKY method is used, the function returns 1 if src1 (or \texttt{src1}^T\texttt{src1} ) is non-singular. Otherwise, it returns 0. In the latter case, dst is not valid. Other methods find a pseudo-solution in case of a singular left-hand side part.

\note If you want to find a unity-norm solution of an under-defined singular system \texttt{src1}\cdot\texttt{dst}=0 , the function solve will not do the work. Use SVD::solveZ instead.

Parameters:: src1 - input matrix on the left-hand side of the system.; src2 - input matrix on the right-hand side of the system.; dst - output solution.; flags - solution (matrix inversion) method (#DecompTypes)

\brief Sorts each row or each column of a matrix.
The function cv::sort sorts each matrix row or each matrix column in ascending or descending order. So you should pass two operation flags to get desired behaviour. If you want to sort matrix rows or columns lexicographically, you can use STL std::sort generic function with the proper comparison predicate.

Parameters:

src - input single-channel array.

dst - output array of the same size and type as src.

flags - operation flags, a combination of #SortFlags

\brief Sorts each row or each column of a matrix.

The function cv::sortIdx sorts each matrix row or each matrix column in the ascending or descending order. So you should pass two operation flags to get desired behaviour. Instead of reordering the elements themselves, it stores the indices of sorted elements in the output array. For example:


    Mat A = Mat::eye(3,3,CV_32F), B;
    sortIdx(A, B, SORT_EVERY_ROW + SORT_ASCENDING);
    // B will probably contain
    // (because of equal elements in A some permutations are possible):
    // [[1, 2, 0], [0, 2, 1], [0, 1, 2]]

Parameters:: src - input single-channel array.; dst - output integer array of the same size as src.; flags - operation flags that could be a combination of cv::SortFlags

\brief Finds the real roots of a cubic equation.

The function solveCubic finds the real roots of a cubic equation: - if coeffs is a 4-element vector:

 \[\texttt{coeffs} [0] x^3 +  \texttt{coeffs} [1] x^2 +  \texttt{coeffs} [2] x +  \texttt{coeffs} [3] = 0\]

- if coeffs is a 3-element vector:

 \[x^3 +  \texttt{coeffs} [0] x^2 +  \texttt{coeffs} [1] x +  \texttt{coeffs} [2] = 0\]

The roots are stored in the roots array.

Parameters:: coeffs - equation coefficients, an array of 3 or 4 elements.; roots - output array of real roots that has 1 or 3 elements.
Returns:: number of real roots. It can be 0, 1 or 2.

\brief Calculates eigenvalues and eigenvectors of a symmetric matrix.

The function cv::eigen calculates just eigenvalues, or eigenvalues and eigenvectors of the symmetric matrix src:


    src*eigenvectors.row(i).t() = eigenvalues.at<srcType>(i)*eigenvectors.row(i).t()

\note Use cv::eigenNonSymmetric for calculation of real eigenvalues and eigenvectors of non-symmetric matrix.

Parameters:: src - input matrix that must have CV_32FC1 or CV_64FC1 type, square size and be symmetrical (src ^T^ == src).; eigenvalues - output vector of eigenvalues of the same type as src; the eigenvalues are stored in the descending order.; eigenvectors - output matrix of eigenvectors; it has the same size and type as src; the eigenvectors are stored as subsequent matrix rows, in the same order as the corresponding eigenvalues.

\brief Calculates the Mahalanobis distance between two vectors.

The function cv::Mahalanobis calculates and returns the weighted distance between two vectors:

 \[d( \texttt{vec1} , \texttt{vec2} )= \sqrt{\sum_{i,j}{\texttt{icovar(i,j)}\cdot(\texttt{vec1}(I)-\texttt{vec2}(I))\cdot(\texttt{vec1(j)}-\texttt{vec2(j)})} }\]

The covariance matrix may be calculated using the #calcCovarMatrix function and then inverted using the invert function (preferably using the #DECOMP_SVD method, as the most accurate).

Parameters:: v1 - first 1D input vector.; v2 - second 1D input vector.; icovar - inverse covariance matrix.

\brief Performs a forward or inverse Discrete Fourier transform of a 1D or 2D floating-point array.
The function cv::dft performs one of the following: - Forward the Fourier transform of a 1D vector of N elements:
```
 \[Y = F^{(N)}  \cdot X,\]
```
where F^{(N)}_{jk}=\exp(-2\pi i j k/N) and i=\sqrt{-1} - Inverse the Fourier transform of a 1D vector of N elements:
```
 \[\begin{array}{l} X'=  \left (F^{(N)} \right )^{-1}  \cdot Y =  \left (F^{(N)} \right )^*  \cdot y  \\ X = (1/N)  \cdot X, \end{array}\]
```
where F^*=\left(\textrm{Re}(F^{(N)})-\textrm{Im}(F^{(N)})\right)^T - Forward the 2D Fourier transform of a M x N matrix:
```
 \[Y = F^{(M)}  \cdot X  \cdot F^{(N)}\]
```
- Inverse the 2D Fourier transform of a M x N matrix:
```
 \[\begin{array}{l} X'=  \left (F^{(M)} \right )^*  \cdot Y  \cdot \left (F^{(N)} \right )^* \\ X =  \frac{1}{M \cdot N} \cdot X' \end{array}\]
```
In case of real (single-channel) data, the output spectrum of the forward Fourier transform or input spectrum of the inverse Fourier transform can be represented in a packed format called *CCS* (complex-conjugate-symmetrical). It was borrowed from IPL (Intel\* Image Processing Library). Here is how 2D *CCS* spectrum looks:
```
 \[\begin{bmatrix} Re Y_{0,0} & Re Y_{0,1} & Im Y_{0,1} & Re Y_{0,2} & Im Y_{0,2} &  \cdots & Re Y_{0,N/2-1} & Im Y_{0,N/2-1} & Re Y_{0,N/2}  \\ Re Y_{1,0} & Re Y_{1,1} & Im Y_{1,1} & Re Y_{1,2} & Im Y_{1,2} &  \cdots & Re Y_{1,N/2-1} & Im Y_{1,N/2-1} & Re Y_{1,N/2}  \\ Im Y_{1,0} & Re Y_{2,1} & Im Y_{2,1} & Re Y_{2,2} & Im Y_{2,2} &  \cdots & Re Y_{2,N/2-1} & Im Y_{2,N/2-1} & Im Y_{1,N/2}  \\ \hdotsfor{9} \\ Re Y_{M/2-1,0} &  Re Y_{M-3,1}  & Im Y_{M-3,1} &  \hdotsfor{3} & Re Y_{M-3,N/2-1} & Im Y_{M-3,N/2-1}& Re Y_{M/2-1,N/2}  \\ Im Y_{M/2-1,0} &  Re Y_{M-2,1}  & Im Y_{M-2,1} &  \hdotsfor{3} & Re Y_{M-2,N/2-1} & Im Y_{M-2,N/2-1}& Im Y_{M/2-1,N/2}  \\ Re Y_{M/2,0}  &  Re Y_{M-1,1} &  Im Y_{M-1,1} &  \hdotsfor{3} & Re Y_{M-1,N/2-1} & Im Y_{M-1,N/2-1}& Re Y_{M/2,N/2} \end{bmatrix}\]
```
In case of 1D transform of a real vector, the output looks like the first row of the matrix above.
So, the function chooses an operation mode depending on the flags and size of the input array: - If #DFT_ROWS is set or the input array has a single row or single column, the function performs a 1D forward or inverse transform of each row of a matrix when #DFT_ROWS is set. Otherwise, it performs a 2D transform. - If the input array is real and #DFT_INVERSE is not set, the function performs a forward 1D or 2D transform: - When #DFT_COMPLEX_OUTPUT is set, the output is a complex matrix of the same size as input. - When #DFT_COMPLEX_OUTPUT is not set, the output is a real matrix of the same size as input. In case of 2D transform, it uses the packed format as shown above. In case of a single 1D transform, it looks like the first row of the matrix above. In case of multiple 1D transforms (when using the #DFT_ROWS flag), each row of the output matrix looks like the first row of the matrix above. - If the input array is complex and either #DFT_INVERSE or #DFT_REAL_OUTPUT are not set, the output is a complex array of the same size as input. The function performs a forward or inverse 1D or 2D transform of the whole input array or each row of the input array independently, depending on the flags DFT_INVERSE and DFT_ROWS. - When #DFT_INVERSE is set and the input array is real, or it is complex but #DFT_REAL_OUTPUT is set, the output is a real array of the same size as input. The function performs a 1D or 2D inverse transformation of the whole input array or each individual row, depending on the flags #DFT_INVERSE and #DFT_ROWS.
If #DFT_SCALE is set, the scaling is done after the transformation.
Unlike dct , the function supports arrays of arbitrary size. But only those arrays are processed efficiently, whose sizes can be factorized in a product of small prime numbers (2, 3, and 5 in the current implementation). Such an efficient DFT size can be calculated using the getOptimalDFTSize method.
The sample below illustrates how to calculate a DFT-based convolution of two 2D real arrays:
```
    void convolveDFT(InputArray A, InputArray B, OutputArray C)
    {
        // reallocate the output array if needed
        C.create(abs(A.rows - B.rows)+1, abs(A.cols - B.cols)+1, A.type());
        Size dftSize;
        // calculate the size of DFT transform
        dftSize.width = getOptimalDFTSize(A.cols + B.cols - 1);
        dftSize.height = getOptimalDFTSize(A.rows + B.rows - 1);

        // allocate temporary buffers and initialize them with 0's
        Mat tempA(dftSize, A.type(), Scalar::all(0));
        Mat tempB(dftSize, B.type(), Scalar::all(0));

        // copy A and B to the top-left corners of tempA and tempB, respectively
        Mat roiA(tempA, Rect(0,0,A.cols,A.rows));
        A.copyTo(roiA);
        Mat roiB(tempB, Rect(0,0,B.cols,B.rows));
        B.copyTo(roiB);

        // now transform the padded A & B in-place;
        // use "nonzeroRows" hint for faster processing
        dft(tempA, tempA, 0, A.rows);
        dft(tempB, tempB, 0, B.rows);

        // multiply the spectrums;
        // the function handles packed spectrum representations well
        mulSpectrums(tempA, tempB, tempA);

        // transform the product back from the frequency domain.
        // Even though all the result rows will be non-zero,
        // you need only the first C.rows of them, and thus you
        // pass nonzeroRows == C.rows
        dft(tempA, tempA, DFT_INVERSE + DFT_SCALE, C.rows);

        // now copy the result back to C.
        tempA(Rect(0, 0, C.cols, C.rows)).copyTo(C);

        // all the temporary buffers will be deallocated automatically
    }
```
To optimize this sample, consider the following approaches: - Since nonzeroRows != 0 is passed to the forward transform calls and since A and B are copied to the top-left corners of tempA and tempB, respectively, it is not necessary to clear the whole tempA and tempB. It is only necessary to clear the tempA.cols - A.cols ( tempB.cols - B.cols) rightmost columns of the matrices. - This DFT-based convolution does not have to be applied to the whole big arrays, especially if B is significantly smaller than A or vice versa. Instead, you can calculate convolution by parts. To do this, you need to split the output array C into multiple tiles. For each tile, estimate which parts of A and B are required to calculate convolution in this tile. If the tiles in C are too small, the speed will decrease a lot because of repeated work. In the ultimate case, when each tile in C is a single pixel, the algorithm becomes equivalent to the naive convolution algorithm. If the tiles are too big, the temporary arrays tempA and tempB become too big and there is also a slowdown because of bad cache locality. So, there is an optimal tile size somewhere in the middle. - If different tiles in C can be calculated in parallel and, thus, the convolution is done by parts, the loop can be threaded.
All of the above improvements have been implemented in #matchTemplate and #filter2D . Therefore, by using them, you can get the performance even better than with the above theoretically optimal implementation. Though, those two functions actually calculate cross-correlation, not convolution, so you need to "flip" the second convolution operand B vertically and horizontally using flip . \note - An example using the discrete fourier transform can be found at opencv_source_code/samples/cpp/dft.cpp - (Python) An example using the dft functionality to perform Wiener deconvolution can be found at opencv_source/samples/python/deconvolution.py - (Python) An example rearranging the quadrants of a Fourier image can be found at opencv_source/samples/python/dft.py
Parameters:

src - input array that could be real or complex.

dst - output array whose size and type depends on the flags .

flags - transformation flags, representing a combination of the #DftFlags

nonzeroRows - when the parameter is not zero, the function assumes that only the first nonzeroRows rows of the input array (#DFT_INVERSE is not set) or only the first nonzeroRows of the output array (#DFT_INVERSE is set) contain non-zeros, thus, the function can handle the rest of the rows more efficiently and save some time; this technique is very useful for calculating array cross-correlation or convolution using DFT.

\brief Calculates the inverse Discrete Fourier Transform of a 1D or 2D array.
idft(src, dst, flags) is equivalent to dft(src, dst, flags | #DFT_INVERSE) . \note None of dft and idft scales the result by default. So, you should pass #DFT_SCALE to one of dft or idft explicitly to make these transforms mutually inverse.

Parameters:

src - input floating-point real or complex array.

dst - output array whose size and type depend on the flags.

flags - operation flags (see dft and #DftFlags).

nonzeroRows - number of dst rows to process; the rest of the rows have undefined content (see the convolution sample in dft description.

\brief Performs a forward or inverse discrete Cosine transform of 1D or 2D array.
The function cv::dct performs a forward or inverse discrete Cosine transform (DCT) of a 1D or 2D floating-point array: - Forward Cosine transform of a 1D vector of N elements:
```
 \[Y = C^{(N)}  \cdot X\]
```
where
```
 \[C^{(N)}_{jk}= \sqrt{\alpha_j/N} \cos \left ( \frac{\pi(2k+1)j}{2N} \right )\]
```
and \alpha_0=1, \alpha_j=2 for *j \> 0*. - Inverse Cosine transform of a 1D vector of N elements:
```
 \[X =  \left (C^{(N)} \right )^{-1}  \cdot Y =  \left (C^{(N)} \right )^T  \cdot Y\]
```
(since C^{(N)} is an orthogonal matrix, C^{(N)} \cdot \left(C^{(N)}\right)^T = I ) - Forward 2D Cosine transform of M x N matrix:
```
 \[Y = C^{(N)}  \cdot X  \cdot \left (C^{(N)} \right )^T\]
```
- Inverse 2D Cosine transform of M x N matrix:
```
 \[X =  \left (C^{(N)} \right )^T  \cdot X  \cdot C^{(N)}\]
```
The function chooses the mode of operation by looking at the flags and size of the input array: - If (flags & #DCT_INVERSE) == 0 , the function does a forward 1D or 2D transform. Otherwise, it is an inverse 1D or 2D transform. - If (flags & #DCT_ROWS) != 0 , the function performs a 1D transform of each row. - If the array is a single column or a single row, the function performs a 1D transform. - If none of the above is true, the function performs a 2D transform.
\note Currently dct supports even-size arrays (2, 4, 6 ...). For data analysis and approximation, you can pad the array when necessary. Also, the function performance depends very much, and not monotonically, on the array size (see getOptimalDFTSize ). In the current implementation DCT of a vector of size N is calculated via DFT of a vector of size N/2 . Thus, the optimal DCT size N1 \>= N can be calculated as:
```
    size_t getOptimalDCTSize(size_t N) { return 2*getOptimalDFTSize((N+1)/2); }
    N1 = getOptimalDCTSize(N);
```
Parameters:

src - input floating-point array.

dst - output array of the same size and type as src .

flags - transformation flags as a combination of cv::DftFlags (DCT_*)

\brief Performs the per-element multiplication of two Fourier spectrums.
The function cv::mulSpectrums performs the per-element multiplication of the two CCS-packed or complex matrices that are results of a real or complex Fourier transform.
The function, together with dft and idft , may be used to calculate convolution (pass conjB=false ) or correlation (pass conjB=true ) of two arrays rapidly. When the arrays are complex, they are simply multiplied (per element) with an optional conjugation of the second-array elements. When the arrays are real, they are assumed to be CCS-packed (see dft for details).

Parameters:

a - first input array.

b - second input array of the same size and type as src1 .

c - output array of the same size and type as src1 .

flags - operation flags; currently, the only supported flag is cv::DFT_ROWS, which indicates that each row of src1 and src2 is an independent 1D Fourier spectrum. If you do not want to use this flag, then simply add a 0 as value.

conjB - optional flag that conjugates the second input array before the multiplication (true) or not (false).

getOptimalDFTSize
```
@Namespace(value="cv")
public static int getOptimalDFTSize(int vecsize)
```
\brief Returns the optimal DFT size for a given vector size.
DFT performance is not a monotonic function of a vector size. Therefore, when you calculate convolution of two arrays or perform the spectral analysis of an array, it usually makes sense to pad the input data with zeros to get a bit larger array that can be transformed much faster than the original one. Arrays whose size is a power-of-two (2, 4, 8, 16, 32, ...) are the fastest to process. Though, the arrays whose size is a product of 2's, 3's, and 5's (for example, 300 = 5\*5\*3\*2\*2) are also processed quite efficiently.
The function cv::getOptimalDFTSize returns the minimum number N that is greater than or equal to vecsize so that the DFT of a vector of size N can be processed efficiently. In the current implementation N = 2 ^p^ \* 3 ^q^ \* 5 ^r^ for some integer p, q, r.
The function returns a negative number if vecsize is too large (very close to INT_MAX ).
While the function cannot be used directly to estimate the optimal vector size for DCT transform (since the current DCT implementation supports only even-size vectors), it can be easily processed as getOptimalDFTSize((vecsize+1)/2)\*2.

Parameters:

vecsize - vector size.

theRNG

public static RNG theRNG()
```
\brief Returns the default random number generator.
The function cv::theRNG returns the default random number generator. For each thread, there is a separate random number generator, so you can use the function safely in multi-thread environments. If you just need to get a single random number using this generator or initialize an array, you can use randu or randn instead. But if you are going to generate many random numbers inside a loop, it is much faster to use this function to retrieve the generator and then use RNG::operator _Tp() .

\brief Fills the array with normally distributed random numbers.
The function cv::randn fills the matrix dst with normally distributed random numbers with the specified mean vector and the standard deviation matrix. The generated random numbers are clipped to fit the value range of the output array data type.

Parameters:

dst - output array of random numbers; the array must be pre-allocated and have 1 to 4 channels.

mean - mean value (expectation) of the generated random numbers.

stddev - standard deviation of the generated random numbers; it can be either a vector (in which case a diagonal standard deviation matrix is assumed) or a square matrix.

\brief Shuffles the array elements randomly.
The function cv::randShuffle shuffles the specified 1D array by randomly choosing pairs of elements and swapping them. The number of such swap operations will be dst.rows\*dst.cols\*iterFactor .

Parameters:

dst - input/output numerical 1D array.

iterFactor - scale factor that determines the number of random swap operations (see the details below).

rng - optional random number generator used for shuffling; if it is zero, theRNG () is used instead.

\brief Finds centers of clusters and groups input samples around the clusters.
The function kmeans implements a k-means algorithm that finds the centers of cluster_count clusters and groups the input samples around the clusters. As an output, \texttt{bestLabels}_i contains a 0-based cluster index for the sample stored in the i^{th} row of the samples matrix.
\note - (Python) An example on K-means clustering can be found at opencv_source_code/samples/python/kmeans.py
Parameters:

data - Data for clustering. An array of N-Dimensional points with float coordinates is needed. Examples of this array can be: - Mat points(count, 2, CV_32F); - Mat points(count, 1, CV_32FC2); - Mat points(1, count, CV_32FC2); - std::vector\ points(sampleCount);

K - Number of clusters to split the set by.

bestLabels - Input/output integer array that stores the cluster indices for every sample.

criteria - The algorithm termination criteria, that is, the maximum number of iterations and/or the desired accuracy. The accuracy is specified as criteria.epsilon. As soon as each of the cluster centers moves by less than criteria.epsilon on some iteration, the algorithm stops.

attempts - Flag to specify the number of times the algorithm is executed using different initial labellings. The algorithm returns the labels that yield the best compactness (see the last function parameter).

flags - Flag that can take values of cv::KmeansFlags

centers - Output matrix of the cluster centers, one row per each cluster center.

Returns:
The function returns the compactness measure that is computed as
```
 \[\sum _i  \| \texttt{samples} _i -  \texttt{centers} _{ \texttt{labels} _i} \| ^2\]
```
after every attempt. The best (minimum) value is chosen and the corresponding labels and the compactness value are returned by the function. Basically, you can use only the core of the function, set the number of attempts to 1, initialize labels each time using a custom algorithm, pass them with the ( flags = #KMEANS_USE_INITIAL_LABELS ) flag, and then choose the best (most-compact) clustering.

\brief Returns a text string formatted using the printf-like expression.
The function acts like sprintf but forms and returns an STL string. It can be used to form an error message in the Exception constructor.

Parameters:

fmt - printf-compatible formatting specifiers.
Note**: |Type|Specifier| |-|-| |const char*|%s| |char|%c| |float / double|%f,%g| |int, long, long long|%d, %ld, %lld| |unsigned, unsigned long, unsigned long long|%u, %lu, %llu| |uint64-> uintmax_t, int64-> intmax_t|%ju, %jd| |size_t|%zu{@code |

\brief Calculates an absolute value of each matrix element.
abs is a meta-function that is expanded to one of absdiff or convertScaleAbs forms: - C = abs(A-B) is equivalent to absdiff(A, B, C) - C = abs(A) is equivalent to absdiff(A, Scalar::all(0), C) - C = Mat_<Vec<uchar,n> >(abs(A*alpha + beta)) is equivalent to convertScaleAbs(A, C, alpha, beta)
The output matrix has the same size and the same type as the input one except for the last case, where C is depth=CV_8U .

Parameters:

m - matrix.

\brief Solve given (non-integer) linear programming problem using the Simplex Algorithm (Simplex Method).
What we mean here by "linear programming problem" (or LP problem, for short) can be formulated as:
```
 \[\mbox{Maximize } c\cdot x\\
 \mbox{Subject to:}\\
 Ax\leq b\\
 x\geq 0\]
```
Where c is fixed 1-by-n row-vector, A is fixed m-by-n matrix, b is fixed m-by-1 column vector and x is an arbitrary n-by-1 column vector, which satisfies the constraints.
Simplex algorithm is one of many algorithms that are designed to handle this sort of problems efficiently. Although it is not optimal in theoretical sense (there exist algorithms that can solve any problem written as above in polynomial time, while simplex method degenerates to exponential time for some special cases), it is well-studied, easy to implement and is shown to work well for real-life purposes.
The particular implementation is taken almost verbatim from **Introduction to Algorithms, third edition** by T. H. Cormen, C. E. Leiserson, R. L. Rivest and Clifford Stein. In particular, the Bland's rule is used to prevent cycling.
Parameters:

Func - This row-vector corresponds to c in the LP problem formulation (see above). It should contain 32- or 64-bit floating point numbers. As a convenience, column-vector may be also submitted, in the latter case it is understood to correspond to c^T.

Constr - m-by-n+1 matrix, whose rightmost column corresponds to b in formulation above and the remaining to A. It should contain 32- or 64-bit floating point numbers.

z - The solution will be returned here as a column-vector - it corresponds to c in the formulation above. It will contain 64-bit floating point numbers.

Returns:

One of cv::SolveLPResult
