yeah, no AI. Its low level computer vision. There is no implicit understanding of the scene to enhance it here. We show the neural nets several examples of low and high quality images it learns a function that makes the low quality looks more like the high quality.

this may make you feel disappointed now, but in the write up we are also pitching this same module to be used in generative networks and other models that do build an understanding of the scene. Lets see what the community (and ourselves) can do next...

Wait, the neural network encodes within itself probability distributions of the various image patches it has seen. This is sort of like AI.

Approaches in the past used heuristics (like finding edges and upsampling them, etc). Those were fragile systems. In this approach, the system learns what's appropriate on its own.

This is not AI in any real sense. It is a fairly straightforward machine learning application to computer vision.
Knowledge is a form of compression
I'm glad to hear that, I feared it might just paste any eyes where it sees some eyes, but like this it might be much closer to what is really in the pixels.
