Webpublic class BFMatcher extends DescriptorMatcher Brute-force descriptor matcher. For each descriptor in the first set, this matcher finds the closest descriptor in the second set by trying each one. This descriptor matcher supports masking permissible matches of descriptor sets. Field Summary Fields inherited from class org.opencv.features2d. WebORB (Oriented FAST and Rotated BRIEF) descriptor is used to find matching keypoints. As a matching function we use number of matching features whose distance is below a given threshold. Identification scenario First we analyse the identificaion scenario, which corresponds to 1:M clasification problem.
