Method Detail

detectEdges

public void detectEdges(@ByVal
                        Mat _src,
                        @ByVal
                        Mat _dst)

\brief The function detects edges in src and draw them to dst.

The algorithm underlies this function is much more robust to texture presence, than common approaches, e.g. Sobel

Parameters:

_src - source image (RGB, float, in [0;1]) to detect edges

_dst - destination image (grayscale, float, in [0;1]) where edges are drawn
