createLSDDetector() [2/2]

Ptr< LSDDetector > cv::line_descriptor::LSDDetector::createLSDDetector ( LSDParam params )

static

Python:
	cv.line_descriptor.LSDDetector.createLSDDetector(		) ->	retval
	cv.line_descriptor.LSDDetector.createLSDDetectorWithParams(	params	) ->	retval

detect() [1/2]

void cv::line_descriptor::LSDDetector::detect	(	const Mat &	image,
		std::vector< KeyLine > &	keypoints,
		int	scale,
		int	numOctaves,
		const Mat &	mask = Mat() )

Python:
	cv.line_descriptor.LSDDetector.detect(	image, scale, numOctaves[, mask]	) ->	keypoints
	cv.line_descriptor.LSDDetector.detect(	images, keylines, scale, numOctaves[, masks]	) ->	None

Detect lines inside an image.

Parameters

image	input image
keypoints	vector that will store extracted lines for one or more images
scale	scale factor used in pyramids generation
numOctaves	number of octaves inside pyramid
mask	mask matrix to detect only KeyLines of interest

detect() [2/2]

void cv::line_descriptor::LSDDetector::detect	(	const std::vector< Mat > &	images,
		std::vector< std::vector< KeyLine > > &	keylines,
		int	scale,
		int	numOctaves,
		const std::vector< Mat > &	masks = std::vector< Mat >() ) const

Python:
	cv.line_descriptor.LSDDetector.detect(	image, scale, numOctaves[, mask]	) ->	keypoints
	cv.line_descriptor.LSDDetector.detect(	images, keylines, scale, numOctaves[, masks]	) ->	None

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters

images	input images
keylines	set of vectors that will store extracted lines for one or more images
scale	scale factor used in pyramids generation
numOctaves	number of octaves inside pyramid
masks	vector of mask matrices to detect only KeyLines of interest from each input image
