Software for detection of duplicate images

[JungerHund]

Hello!

If my post does not belong in this forum, please let me know and I will delete it.

Before uploading images, I usually try to avoid duplicates (compared to previous, thematically similar uploads).
So far I have used three different programs for this:

• Anti Twin (very slow, few configuration options, but quite good results)
• VisiPics (fast, few configuration options, useful results)
• Duplicate Photo Cleaner (medium speed, some configuration options, good results)

Interestingly, each of these programs find some duplicate images that the other two cannot. So there seem to be differences in the search algorithms and/or their implementation.

Hence my question: do you know of other programs with which you have had good experiences in eliminating duplicate images?

Thank you for your help!
