public double getClipLimit()

apply

public void apply(Mat src,
                  Mat dst)

Equalizes the histogram of a grayscale image using Contrast Limited Adaptive Histogram Equalization.

Parameters:

src - Source image of type CV_8UC1 or CV_16UC1.

dst - Destination image.

collectGarbage

public void collectGarbage()

setClipLimit

public void setClipLimit(double clipLimit)

Sets threshold for contrast limiting.

Parameters:

clipLimit - threshold value.

setTilesGridSize

public void setTilesGridSize(Size tileGridSize)

Sets size of grid for histogram equalization. Input image will be divided into equally sized rectangular tiles.

Parameters:

tileGridSize - defines the number of tiles in row and column.

finalize

                 throws Throwable

Overrides:

finalize in class Algorithm

Throws:

Throwable
