I'm aware there are tons of programs that allow you to search a given folder for duplicate images and delete them, but are there any [programs/extensions/executables] that will function as an extension of Windows Explorer itself and allow me to sort my pictures by how visually-similar they are, so that I can then use Explorer to browse them and choose whether or not to delete the duplicates?

Thanks, I would really appreciate an answer to this.

  • There are many with facial recognition (Picassa, ...) and I know that Facebook has a kick ass recognition algorithm, but I'm not aware of any that could be installed on the desktop – Tomap Dec 26 '17 at 7:28
  • You have a tough time defining visually similar. Even Google doesn't do this well. – Sherwood Botsford Jan 25 '18 at 18:05
  • @SherwoodBotsford How so? I was under the impression image recognition algorithms are sufficiently mature nowadays. Is this not the case? I know Facebook's is advanced enough to more or less accurately determine the contents of an image, which it uses to automatically generate alt text. Relative to that, defining by colour seems like it should be a lot simpler. – Hashim Jan 26 '18 at 5:25
  • Try this: Find an interesting image. Drag it into the search bar on google. If you ask it find all sizes, it's pretty good. But down a couple lines there's a find similar images. I did this orginially searching for mountains and meadow. Google guessed "Teletubbies have kids" when I clicked show similar that's what I got. – Sherwood Botsford Jan 26 '18 at 22:42
  • @SherwoodBotsford You’ve misunderstood this question. – Hashim Jan 30 '18 at 21:47

Have you looked at applications based on Clarifai's imgsort API? It's the basis for quite a number of very effective enterprise level image sorting/blocking/detecting applications.

There are many java and python apps doing one type of sort or another and many are free and available on github.
