Typically, recreating a celebrity as an animated 3D character requires painstaking modeling based on motion capture and laser scans. In the future, though, all you'll need is a few limo-chasing photographers. University of Washington researchers have developed a system that creates digital face "puppets" by running a collection of photos -- in this case, paparazzi shots -- through special face tracking software. The digital dopplegangers (such as Kevin Spacey and Arnold Schwarzenegger) bear an uncanny resemblance to their real-world counterparts, but are sophisticated enough to mimic the expressions of virtually anyone else.
