__fromPtr__()

static

computeOrientation()

void OpenCVForUnity.XimgprocModule.StructuredEdgeDetection.computeOrientation	(	Mat	src,
		Mat	dst
	)

The function computes orientation from edge image.

Parameters

src	edge image.
dst	orientation image.

detectEdges()

void OpenCVForUnity.XimgprocModule.StructuredEdgeDetection.detectEdges	(	Mat	src,
		Mat	dst
	)

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
