ABSTRACT
The face is a complex and highly mobile object whose detailed topological configuration varies widely between individuals. This chapter discusses the behavioral information carried by facial expressions. It focuses on both the analysis and the synthesis of facial expressions (Figure 5.1). The term “face synthesis” indicates a class of problems aimed at synthesizing a model of a static face. The term “facial synthesis” is defined as a process of modeling facial appearance. Facial topology is a behavioral characteristic called facial expression, the visible result of synthetic emotion indicated in the face.
