Jumping the Uncanny Valley: Hyper-Realistic 3D Actors
Uncanny valley theory refers to a gap in emotional response to humanoid robots and CGI characters. There's a point where people feel creeped out by near-realistic human fakes when they take on an almost real but not-quite-right look. Think corpses, or zombies.
That valley may have been crossed by computer graphics company Image Metrics. They've recently released a mind blowing video sample that demonstrates their new facial animation technology. In a nutshell, they record movements of a human actor, and can replicate and control facial micro-movements down to the pixel.
