Can a application be developed specifically for finding photo duplicates and similar photos. I have tried to run duplicate finder and have successively found and removed some duplicates though does not detect all my duplicates. These are pictures that are 100% duplicates. After scanning and removing what was able to be found and removing duplicates and deleting trash can I ran duplicates finder again. It said no duplicates. Tried other duplicates software and found 120 duplicates of the exact same image. As well as many others. I was shocked and could free up an additional 58 gig of space. I did regain some space from Parallels Duplicate finder but could use the additional 58 gig of duplicates this other software found.
