Facial animation  
These folks have developed a facial animation tool that works purely by computer vision. Basically, you give it video of people acting like people and it will move a computer-modeled face to match. This is the kind of work that traditionally requires a lot of animator-time and is really painstaking and obnoxious.

But more importantly -- go to their site and hit "play" on the big video. The match-up isn't quite perfect, but it's *very* impressive, especially on such a differently-shaped modeled face. Some of the "not quite perfect" is just that the face the computer is controlling doesn't look much like the woman they're filming.

That's pretty impressive; though the lack of forehead-wrinkling muscles seems to be both something simple to resolve (given all the problems they've already tackled, like lip movement) and extremely valuable for adding in believable sadness/confusion faces. It's still a big fake side-by-side (maybe add in some more around-the-eye "muscles"?), but wow.

Yeah. It's definitely not perfect, but it's *much* better than any other automated tool I'm familiar with.

The guy I got it from also mentioned that they don't do anything with open mouths, so no lip-synching. Presumably they're working on that one.

I'm still in awe. Thanks for sharing.
