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.

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. –  the-kenny 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)... –  foregon May 2 at 15:05
