Looks cool, but what do you do with the image once uploaded? The FAQ says "Yes, we take security very seriously and ensure that all images uploaded to our platform are protected. Enhancing image quality is safe and reliable." and the Privacy policy looks very generic and not specific to your service.

Are the images deleted after x days? Do you keep to train again? What rights (if any) are you claiming once I use it?

Not as good yet (at least in this case): * original: https://upcdn.io/12a1z2u/image/uploads/2024/07/18/4kU68cBDKF... * "10K" enhanced: https://replicate.delivery/czjl/gFpKKIlEKKZrL1lfqxXlpQrOBbe9...

The original contains artifacts that tend to arise after compression, as the other poster notes (posterization and such). I wonder if you'll get better results if you make the original go through a gaussian to smooth those artifacts, and then feed it to the enhancer.

Wouldn't that effectively just be losing input resolution?

Earlier quoted context omitted.

These enhance effects typically use guesswork. That would be useful to gain hints, but not to know for sure what the original looked like.

Unless the rest of the image offers details that the human observer would ignore but the AI would pick up. E.g. low res photo from 1828 of a US president - enhance to John Quincy Adams. Surprisingly there's a daguerreotype of John Quincy Adams from 1843[1], the AI could use that; perhaps "enhance" the time backwards a bit, to make him 15 years younger.

Right, and that would be guesswork unless the image had been explicitly tagged.

Yes. Well, kinda. You can maintain the resolution, but you'll be losing information regardless.

But that's what's needed here. The current image contains a lot of compression artifacts, which are extraneous information, and that's what the upscaler seems to want to enhance. Wipe that information out and you're left with the rough structure, which is what we actually want enhanced.

AI is gonna introduce new information to input new resolution from nowhere either which way, so we're just priming and massaging and optimizing our input so as to remove any obstructions that might trip up the AI enhancer. But yes you're right, ideally the enhancer should know how to take into account compression artifacts but this one doesn't.
