The BRISK constructor for a custom pattern

引数

radiusList	defines the radii (in pixels) where the samples around a keypoint are taken (for keypoint scale 1).
numberList	defines the number of sampling points on the sampling circle. Must be the same size as radiusList..
dMax	threshold for the short pairings used for descriptor formation (in pixels for keypoint scale 1).
dMin	threshold for the long pairings used for orientation determination (in pixels for keypoint scale 1).
indexChange	index remapping of the bits.

◆ create() [2/3]

static CV_WRAP Ptr< BRISK > cv::BRISK::create	(	int	thresh,
		int	octaves,
		const std::vector< float > &	radiusList,

	)

static

The BRISK constructor for a custom pattern, detection threshold and octaves

引数

thresh	AGAST detection threshold score.
octaves	detection octaves. Use 0 to do single scale.
radiusList	defines the radii (in pixels) where the samples around a keypoint are taken (for keypoint scale 1).
numberList	defines the number of sampling points on the sampling circle. Must be the same size as radiusList..
dMax	threshold for the short pairings used for descriptor formation (in pixels for keypoint scale 1).
dMin	threshold for the long pairings used for orientation determination (in pixels for keypoint scale 1).
indexChange	index remapping of the bits.

static

The BRISK constructor

引数

thresh	AGAST detection threshold score.
octaves	detection octaves. Use 0 to do single scale.
patternScale	apply this scale to the pattern used for sampling the neighbourhood of a keypoint.

◆ setOctaves()

virtual CV_WRAP void cv::BRISK::setOctaves ( int octaves )

inlinevirtual

Set detection octaves.

引数

octaves detection octaves. Use 0 to do single scale.

◆ setThreshold()

virtual CV_WRAP void cv::BRISK::setThreshold ( int threshold )

inlinevirtual
