Pictures Perfect

What you're seeing in this video from graphics processing firm Nvidia is the result of two algorithmic adversaries trying to one-up each other. Working from a photo database of 30,000 celebrity faces, the two algorithms learned about different details, like beards and jewelry, that make a face look real to the human eye, and then engaged in a rapid-fire back-and-forth process that produced amazingly realistic results. None of the good-looking folks you see are real, but you'd never know it.
