Paper in IEEE CVPR (1994) on A Vision system for observing and extracting facial action parameters”

Abstract We describe a computer vision system for observing the “action units” of a face using video sequences as input. The visual observation (sensing) is achieved by using an optimal estimation optical flow method coupled with a geometric and a physical (muscle) model describing the facial structure. This modeling results in a time-varying spatial patterning […]
