Simulation of facial muscle actions based on rational free form deformations

This paper describes interactive facilities for simulating abstract muscle actions using rational free form deformations (RFFD). The particular muscle action is simulated as the displacement of the control points of the control-unit for an RFFD defined on a region of interest. One or several simulated muscle actions constitute a minimum perceptible action (MPA), which is defined as the atomic action unit, similar to action unit (AU) of the facial action coding system (FACS), to build an expression
