I found these incredible Youtube videos on artificially generated faces posted by Tero Karras, a researcher at Nvidia.
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.
This has implications for the modeling world and eventually the acting profession too. Once faces and bodies can be made to move and speak like a human being, actors will undoubtedly find less work.
