WebBrute-Force Matcher. Brute-Force matcher is simple. It takes the descriptor of one feature in first set and is matched with all other features in second set using some distance calculation. And the closest one is returned. For BF matcher, first we have to create the cv.DescriptorMatcher object with BFMatcher as type. It takes two optional params.

Webmatching speed can translate to very high gains in real ap-plications. Fast and light weight descriptor methods in-clude BRISK [33], BRIEF [10] and ORB [53], however, their matching capability is often inferior to standard hand-crafted features such as SIFT [39] and SURF [7], as pre-sented by Heinly J. et al. [26]. In challenging scenarios, Webnary Local Image Descriptor), a very e cient binary local im-age descriptor. We use AdaBoost to train our new descriptor with an unbalanced data set to address the heavily asymmetric image matching problem. To binarize our descriptor we min-imize a new similarity loss in which all weak learners share a common weight.
