The design of a Syntax-directed facial animation system

Abstract

A sytax-directed approach is proposed to avoid the inflexibility problem occurred in most of the existing facial animation systems. Our system contains a region-based face model and provides a developing environment for users to describe the behaviors of action units and the needed facial expressions via writing sentences. The syntax and semantics of the language can be redefined interactively and the kernel of the proposed system is always the same. We demonstrate the feasibility of syntax-directed facial animation system on a window-based personal computer. with the function of texture mapping, our system can generate very realistic facial expressions. Experiment shows that our system is a very flexible and effective tool for the presentation of human facial animations
