class	cv::xfeatures2d::BriefDescriptorExtractor
	Class for computing BRIEF descriptors described in [33] . More...
class	cv::xfeatures2d::DAISY
	Class implementing DAISY descriptor, described in [203]. More...
class	cv::xfeatures2d::Elliptic_KeyPoint
	Elliptic region around an interest point. More...
class	cv::xfeatures2d::FREAK
	Class implementing the FREAK (Fast Retina Keypoint) keypoint descriptor, described in [4] . More...
class	cv::xfeatures2d::HarrisLaplaceFeatureDetector
	Class implementing the Harris-Laplace feature detector as described in [149]. More...
class	cv::xfeatures2d::LATCH
class	cv::xfeatures2d::LUCID
	Class implementing the locally uniform comparison image descriptor, described in [245]. More...
class	cv::xfeatures2d::MSDDetector
	Class implementing the MSD (Maximal Self-Dissimilarity) keypoint detector, described in [204]. More...
class	cv::xfeatures2d::PCTSignatures
	Class implementing PCT (position-color-texture) signature extraction as described in [114]. The algorithm is divided to a feature sampler and a clusterizer. Feature sampler produces samples at given set of coordinates. Clusterizer then produces clusters of these samples using k-means algorithm. Resulting set of clusters is the signature of the input image. More...
