I'm looking for an "automatic" method to rate/compare the quality of 2 (or more) images which are detected as duplicates by other tools.

=====

Let's say, in my image dump, I have several images both in JPG & PNG, different resolutions & sizes. I'm looking for a method to determine which one is "best quality".

Usually, I rate this "by hand" by the following:

• Higher resolution first
• PNG > JPG
• File size

The problem with that approach is that some images are upscaled versions of the original, so maybe it has a better resolution, but it's blurry/JPEG-crustified...

At this point, a research on the web either returns:

• Dedup utilities => Not what I'm looking for, I already use czkawka.
• Online solutions (upload your images and get a comparison) => I want something that runs locally, and in worst case something I can self-host
• "AI"-powered solutions => Often online (see above item), or without any way to self-host.
• A few research article, but more focused around photography and rating the sensors capabilities, or satellite imagery.

If you have a solution for this, I'd gladly take your feedback.

And if that's a scientific paper/research article, I have no problem in attempting to code the described algorithm/formula into a tool to automatize the process.

The idea would be to have a tool that would tell me, between duplicates of my images, which one is the best quality (read, with the less amount of compression artifact, and higher resolution)
