Abstract
In the domain of telecommunication applications, videophony, teleconferency, the representation and modelization of human face, and its expressions, knows an important development. In this paper, we present the basic principles of image sequences coding with main approaches and methods to lead to 3D model-based coding. Then, we introduce our 3D wire-frame model with which we have developed some compression and triangulated surface representation methods. An original approach to simulate and reproduce facial expressions with radial basis functions is also presented.
