The function detects edges in src and draw them to dst

dst = obj.detectEdges(src)

Input

• src source image (RGB, float, in [0;1]) to detect edges.

Output

• dst destination image (grayscale, float, in [0;1]) where edges are drawn.

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