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 cv.BFMatcher (). It takes two optional params.
WebJan 11, 2016 · Our panorama stitching algorithm consists of four steps: Step #1: Detect keypoints (DoG, Harris, etc.) and extract local invariant descriptors (SIFT, SURF, etc.) from the two input images. Step #2: Match the descriptors between the two images. Step #3: Use the RANSAC algorithm to estimate a homography matrix using our matched feature vectors.
