Abstract
Nowadays there are not any reliable systems able to codify a video streaming according to the FACS. The few system that are able to do it works on frontal, or however not natural postures. The system we propose, takes advantage from a robust 3D tracking based on a 3D template, in order to extract some features correlated to the facial expressions. Moreover, this system provides for each feature a reliability level according to the presence of some occlusions, or due to some errors in tracking that could hide or make the reconstruction on the template, become critical.
