Function Documentation

createFastLineDetector()

Ptr<FastLineDetector> cv::ximgproc::createFastLineDetector	(	int	_length_threshold = 10,
		float	_distance_threshold = 1.414213562f,
		double	_canny_th1 = 50.0,
		double	_canny_th2 = 50.0,
		int	_canny_aperture_size = 3,
		bool	_do_merge = false
	)

Python:
	retval	=	cv.ximgproc.createFastLineDetector(	[, _length_threshold[, _distance_threshold[, _canny_th1[, _canny_th2[, _canny_aperture_size[, _do_merge]]]]]]	)

#include <opencv2/ximgproc/fast_line_detector.hpp>

Creates a smart pointer to a FastLineDetector object and initializes it.

Parameters

_length_threshold	10 - Segment shorter than this will be discarded
_distance_threshold	1.41421356 - A point placed from a hypothesis line segment farther than this will be regarded as an outlier
_canny_th1	50 - First threshold for hysteresis procedure in Canny()
_canny_th2	50 - Second threshold for hysteresis procedure in Canny()
_canny_aperture_size	3 - Aperturesize for the sobel operator in Canny(). If zero, Canny() is not applied and the input image is taken as an edge image.
_do_merge	false - If true, incremental merging of segments will be perfomred
