This paper describes a method to create a facial expression of a virtual character inhabiting in the virtual environment. The proposed method is to search for facial expression from a facial image and to map the expression to a virtual character. In general, it is a time-consuming and laborious job to create a facial expression manually. In order to extract components of facial expression from facial images automatically, Genetic Algorithms and Simulated Annealing are used. With the proposed method a realistic facial expression of the virtual character can be created more easily and efficiently.
