WebBasics of Brute-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 BFMatcher object using cv2.BFMatcher (). It takes two optional params.
