class | cv::xfeatures2d::LUCID |
Class implementing the locally uniform comparison image descriptor, described in [305]. More... | |
class | cv::xfeatures2d::MSDDetector |
Class implementing the MSD (Maximal Self-Dissimilarity) keypoint detector, described in [255]. More... | |
class | cv::xfeatures2d::PCTSignatures |
Class implementing PCT (position-color-texture) signature extraction as described in [139]. 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... | |
