I'm searching for an application to find duplicate images.

In my Linux days, there was a nice Gtk+ application which I could provide some folders and which would list all duplicate images based on some algorithm to determine image-equality (It could detect duplicate images even if one image had a lower resolution or was color shifted) It was also possible to modify the threshold to prevent false-positives.

So far, I found nothing for Mac OS X which could do this.

Nice GUI is a plus.

    I realize that it's off-topic, but what was the name of the Linux app? – LOlliffe Sep 11 '14 at 23:53

dupeguru picture ed is free and does exactly that. http://www.macupdate.com/app/mac/22724/dupeguru-picture-edition

    Very good! How can I move duplicates to trash? The only option I can find is "Move to trash and replace with hardlinks". Do I miss something? Edit: Please ignore. Just found it. It's the first option. – jsadfeew Jan 4 '11 at 19:57
  • Another option is a paid app called 'PhotoBrain' - does the same thing as dupeGuru PE but is just a bit fancier with its UX including allowing you to specify the image to search for dupes for (within what folder)... – user46942 May 2 '14 at 15:05
