Sift knnmatch
WebMay 31, 2024 · updated May 31 '18. if you use knnMatch, it will return a list of (the best) K matches instead of a single DMatch. (K=2 was chosen in your example) using match instead will return a single list of matches. (that's probably, what you expected) 1. prinsherbert (May 31 '18) edit. vladvin (Jan 27 '0) edit. add a comment. WebMay 31, 2013 · Please if someone want to confirm It would help. This script extract first 100 keypoints on an image then extract 1 keypoint. Both set of descriptors are stored inside the matcher with .add. Then if you run it you will see that using .match the code works. Using knnMatch the matcher doesnt' return anything:
