I am trying to implement this paper on copy-move forgery in matlab. I have created clusters using selected keypoints. And now I need to identify the matching clusters and mark them with each other . But I could not find any understandable method to match the clusters. It would be helpful if someone could advice me on this. As an example, I extracted and marked clusters in the below image

The Computer Vision System Toolbox has SURF, which is like SIFT. You'll just have to figure out how to implement the paper with the function. See https://www.mathworks.com/help/vision/ug/local-feature-detection-and-extraction.html?searchHighlight=sift&s_tid=doc_srchtitle

OK, good luck. If it ends up being too much work, maybe you can see if the authors will sell you their software that does it already, and save you a lot of time.
