Member Function Documentation

virtual void cv::ximgproc::StructuredEdgeDetection::computeOrientation	(	cv::InputArray	_src,
		cv::OutputArray	_dst
	)		const

pure virtual

Python:
	_dst	=	cv.ximgproc_StructuredEdgeDetection.computeOrientation(	_src[, _dst]	)

The function computes orientation from edge image.

Parameters

_src	edge image.
_dst	orientation image.

virtual void cv::ximgproc::StructuredEdgeDetection::detectEdges	(	cv::InputArray	_src,
		cv::OutputArray	_dst
	)		const

pure virtual

Python:
	_dst	=	cv.ximgproc_StructuredEdgeDetection.detectEdges(	_src[, _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

virtual void cv::ximgproc::StructuredEdgeDetection::edgesNms	(	cv::InputArray	edge_image,
		cv::InputArray	orientation_image,
		cv::OutputArray	_dst,
		int	r = `2`,
		int	s = `0`,
		float	m = `1`,
		bool	isParallel = `true`
	)		const

pure virtual

Python:
	_dst	=	cv.ximgproc_StructuredEdgeDetection.edgesNms(	edge_image, orientation_image[, _dst[, r[, s[, m[, isParallel]]]]]	)

The function edgenms in edge image and suppress edges where edge is stronger in orthogonal direction.

Parameters

edge_image	edge image from detectEdges function.
orientation_image	orientation image from computeOrientation function.
_dst	suppressed image (grayscale, float, in [0;1])
r	radius for NMS suppression.
s	radius for boundary suppression.
m	multiplier for conservative suppression.
isParallel	enables/disables parallel computing.
