SPECIFIC FACE SYNTHESIS BASED ON THE MODIFICATION OF THE GENERAL FACE MODEL

Much attention has been placed on the human face synthesis techniques in the field of computer animation because of the wide use foreground．It can be used in the human language perception model investigation，virtual environment，telecommunication technique，education，medicine，film，game and entertainment etc．As a result of the differences among faces in the reality，general human face model individuality becomes a key technique of human face synthesis．The determinant differences among faces are geometrical features and texture features．According to the facial geometrical features of a specific person，global and local transformation is applied to accomplish the modification from neutral general face model to neutral specific face model．After this，vector space displacement transformation is designed to generate the basic expression of specific face model based on the hypothesis that both the neutral and the basic expressions of general facial model had already been known．At last，multi-direction texture mapping technique is presented in this paper to enhance the realistic synthesized results of the specific human face．
