Computer based 3D face model has been widely used in many fields, such as virtual reality, computer aided instruction, teleconference, HCI, computer game, movie making, etc. The method of Dvalue is presented to realize the generation of personalized 3D face model by modificating a generic 3D face model only from front view and side view face images. On the basis of the generated personalized 3D face model, face animation system based on MPEG4 framework is realized. The experimental result is better.
