Google's Incredible New Photo AI Makes 'Zoom And Enhance' a Real Thing
DAVID NIELD 7 SEPTEMBER 2021
You may well have seen sci-fi movies or television shows where the
protagonist asks to zoom in on an image and enhance the results –
revealing a face, or a number plate, or any other key detail – and
Google's newest artificial intelligence engines, based on what's known
as diffusion models, are able to pull off this very trick.
The technique is called natural image synthesis by Google, and in this
particular scenario, image super-resolution. You start off with a
small, blocky, pixelated photo, and you end up with something sharp,
clear, and natural-looking. It may not match the original exactly, but
it's close enough to look real to a pair of human eyes.
This is really remarkable! It should be a big help to improve low
quality photos of criminals caught in the act.
