You can upscale a 170x170 image yourself, if you're not familiar with what that ...

That is not true

For example see

That example isn't doing any scaling.

You can try to guess the location of edges to enhance them after upscaling, but it's guessing, and when the source has the detail level of a 170x170 moon photo a big proportion of the guessing will inevitably be wrong.

And in this case it would take a pretty amazing unblur to even get to the point it can start looking for those edges.

You're mistaken and the original experiment does not distinguish between classic edge aware upscaling/super resolution vs more problematic replacement

I'm mistaken about which part? Let's start here:

You did not link an example of upscaling, the before and after are the same size.

Unsharp filters enhance false edges on almost all images.

If you claim either one of those are wrong, you're being ridiculous.

I think if you paste our conversation into ChatGPT it can explain the relevant upsampling algorithms. There are algorithms that will artificially enhance edges in a way that can look like "AI", for example everything done on pixel phones prior to ~2023

And to be clear, everyone including Apple has been doing this since at least 2017

The problem with what Samsung was doing is that it was moon-specific detection and replacement
