Method Detail

detect

public void detect(@ByVal
                   Mat src,
                   @ByVal
                   Mat lines,
                   @ByRef(nullValue="cv::cuda::Stream::Null()")
                   Stream stream)

\brief Finds lines in a binary image using the classical Hough transform.

Parameters:

src - 8-bit, single-channel binary source image.

lines - Output vector of lines. Each line is represented by a two-element vector (\rho, \theta) . \rho is the distance from the coordinate origin (0,0) (top-left corner of the image). \theta is the line rotation angle in radians ( 0 \sim \textrm{vertical line}, \pi/2 \sim \textrm{horizontal line} ).

stream - Stream for the asynchronous version.
