[FRIAM] This is scary, and yet very cool...Ai neural networks making pictures, look really good

[Marcus Daniels]

The idea [1] is that they learn the distribution function of different kinds of distortion using a machine learning algorithm.
Then that algorithm can invert that distribution function.  Kind of like a lens can correct for nearsightedness.

Stumbled across this looking for a way to gently adjust some old pictures of mine without watermarks (gigapixel), photoshop wasn't cutting it  because not enough pixels or data in the originals.

I am beyond fascinated how do they do it? just guess based on colors and add more pixels with that color?
