BTW, I'm currently working on something I internally call "Rough Image Hash". It should make identifying similar images near-automatic or at least very easy. And it will be scale-invariant, brightness-invariant, saturation-invariant, hue-tolerant, and, of course, blindingly fast. So you will be able to find "Image Dupes", and you'll get "Perceptual Sorting" in the file list.

Sounds interesting. So how would it handle simple changes to aspect ratio or rotation? Typically after getting home from a trip, I'll spend some time manipulating photos a bit. Nothing dramatic - just some minor rotation if I had a horizon tilted (which also results in some cropping) or cropping photos from a camera 4:3 to 16:9. In some instances I may lighten or darken slightly but very rarely.

Wow, AI wetness!!!
Jokes aside, that's an uber-welcome feature. Sometimes I really need to find image dupes and have to resort to a third party, now defunct, utility. Glad to see that coming!

We'll see. It won't be learning, but I'll be learning...

Ok, I'm learning... Looks like it's a *little* harder than I thought initially and I'm not sure yet if that *little* is ironic. But I'm still optimistic...

What formats does this actually support Don, or what criteria is used to decide?, I couldn't ascertain because those I have codecs for like WebP don't work for me, whereas HEIF does though, so is it based on codec support or a fixed list of extensions?.

Also, it's just a suggestion, I think it would be good to open Tolerance up to quicksearch if it's not too difficult, maybe something like #image.hash: 4 == 18cde751667618ce

"WebP don't work for me"... no hash is generated?

WebP does work for me. There are no limitations AFAIK. All images that can be shown should be hashable.

Hmm not what I experience.

All those file types have thumbnails and hover box?

Yes.
I think for some filetypes the issue is x64 related, even though for WebP I have x86 codec installed too.

Ah yes, that might be. 64-bit thumbnails are currently not supported by the image hash.

Nevertheless, I worked on it a bit and the next beta might give other results.

It seems to be generating more hashes but all the items get duplicated with ImageHash suffix filenames of non existent files, and it doesn't complete, so its hard to tell.

Fuck, forgot to remove a line of debug code. Wait...

Okay, download v24.60.0118 again.

Yep WebP are working now, not sure the factors at play regarding the others that still don't though.
