@lucy I tried the SIFT code given on the site http://www.vlfeat.org/overview/sift.html and ran the code on MATLAB 2013a. But this is for detecting and extracting features in two different images and then matching the same. Plz help to detectextract and even MATCH keypoints in a single image.(Basically I want to detect copy move forgery)
