That said, while I was waiting for my post to be accepted, I kept tinkering around and was able to get this working: WebThe general steps of the algorithm are : 1. Finding the SIFT keypoints(kp) and the descriptors(d) of the Target image: 1. Generate a SIFT feature database (Dictionary in our case) of all the query image. 1. Compare the features of the target image to each of the query features in the database. (either FLANN or BruteForce matcher can be used) 1.
