The bullshit "image enhancement" button that they have in shows like CSI is finally leaving the realm of science fiction and entering reality, where it can be revealed that "enhancing" an image from data you don't have is just a word for "making shit up"https://twitter.com/nickstenning/status/1274374729101651968?s=20 …

Don't want to derail your point but the CSI "image enhancement" thing is real now. Not going to promote any specific tool but they all use AI algorithms now and do a decent job > https://www.google.com/search?q=upscale+image+ai …

I don't see how it can be, at least to the degree used in popular visual art. You can't extract data that aren't there. You can perhaps draw inferences, but they're guesses. If a vehicle plate is 40 pixels in the original, no way will you get a number from it with certainty.

Yeah look this is the thing, "upscaling" is useful only in the aesthetic sense, not in the sense of actually giving you any info you don't have When you squint at a blurry photo to try to figure out what it "really" looks like, you're upscaling using your brain

A computer doing it for you is just saving you the labor of using your visual cortex's processing power and your own thousands of hours of "training data" of what things look like So you can watch old tapes of TV shows broadcast in SD and it's more pleasant to do so

But it's never actually doing work that you couldn't be doing for yourself It can never actually show you something that was genuinely *hidden* by the low resolution It doesn't know what the actor's face "really" looks like, it's guessing same as you are
