I have a large number of scanned images of photographs. They are scanned from prints, and for some images there are several prints. I would like to find a program that would group similar images (similar in some sense that approximates human perception of similarity) and flags the slight differences within a group. I've looked on Google and found a few programs for criminal investigation but they want $ and seem only to exist for Windows, which I don't have here.
I imagine that similarities could be found by image subtraction with minimization of some measure of image difference. But I also imagine that there are a host of complications.
