Abstract
We present a set of hierarchical expression rules based on which facial expression analysis in facial images can be carried out. The proposed expression rules describe an expression as a combination of facial actions, and a facial action as a combination of FFP movements. The FFP movements are specified both in direction range and in magnitude range. As the hierarchy of the expression rules indicates, facial expression analysis boils down to the FFP tracking. We adopt a model-based approach to accomplish this task. Possible applications of expression analysis are presented, which include expression recognition, facial image retrieval, and facial expression agent. Backgrounds of these applications are introduced and related key technologies are discussed.
