FaceMotion Technical Preview
FaceMotion is a facial tracking programme which allows users to track their facial movements using small markers on their face, and record with one a single camera.
FaceMotion is desinged to work with a head mouted camera, but it has the capabilites to record from a fixed camera and to stablize the face, allowing for a better track.
The difference about FaceMotion is that in employs a fuzzy logic system to convert the marker animation into a FACS type standard allowing for easier migration of the performers intent into other 3d modelling packages.
Here is a video on FaceMotion as it tracks a head for the facial preformance.here
