best "duplicate finder" for image & video?

blablarg18

I need something that can look into the human-visible contents of image or video files and tell me about likely duplicates. Matching on file name, byte contents, size, etc. is not good enough.

For images, I've tried Visipics and Awesome Duplicate Photo Finder. They're OK for finding near-exact matches.

But they miss a lot of matches where the difference is cropping: in other words, a human looking at 2 images can see that one crops or overlaps another making them conceptually the same, but Visipics or ADPF will not see the match. What other app would be good?

And for finding video content matches, I have no idea. Last time I checked, apps only matched on file byte contents (not very useful). What content matching app would be good for video?

Hello,

I use "fslint". It't easy to use, fast, and flexible. Unfortunately, it is not available for windoZe.

see: https://alternativeto.net/software/fslint/?platform=windows which lists alternatives to fslint. I have not used any of them as I run gnu-linux exclusively, but it seems like a good place to start.

Ooops! I just read your post more carefully. I have NO CLUE if there is any good software to do what you are asking. I imagine it would be VERY difficult to write and be god-awful slow if it actually worked.

I am a fan of dupeGuru, which supports fuzzy matching that should help with crops and overlays. It doesn't work on videos, but it does work on still images.

@jsl76 Thanks. dupeGuru found a few more!
I had to set the "filter hardness" quite low, like to 20 (lots of false positives)... but it was fun.
