Face modeling and the establishment of facial expression on the face by computer and portrait of exaggerating treatment is a hot research topic at present, its technology and products have broad application prospects and great economic benefits. For example, distance learning, entertainment, video games,video telephony and all so the technology are all likely to be used distance learning, entertainment, video games,video telephony and all so. the current research in the subject analysis from home and abroad, the complexity of human facial expression, Specificity of face structure, so there are many issues still need in-depth study and discussion.Current facial expression animation facial deformation technology and the technology There has been a lot of research methods in facial expression animation technology and facial deformation techniques at present, on the one hand this paper analyzes and summarizes the previous methods of facial expression animation technology and facial deformation techniques; the other hand studying human facial expression feature on the basis of previous analysis,selecting an appropriate method for facial expression animation technology and facial deformation techniques, designing a system that can achieve a cartoon face animation by allowing the two together.In the face animation system design, the paper firstly analysis a positive face image, counts facial features points and locate s a particular human face by using the method of ASM (Active Shape Model) in order to achieve the key parts of the face match. then the human face as a flexible geometry by combining with elastic deformation theory, the paper studies generating algorithm of human facial expression animation and proposes an eyebrow movement algorithm deformation theory based on elastic deformation theory on the basis of facial expression in people who have eye movement and mouth movement then driving facial expression of the three most critical parts:eyes, mouth and eyebrows by data of expression unit,who together to a whole to achieve different expression of facial expression. Finally, using exaggerated deformation processing of the human face, generating a sense of humor, exaggerated effects of face picture be based on image mapping algorithm, exaggerated deformation processing of the human face. The remarkable characteristic of the system is that it can achieve the animation effect by using different combinations of expression units including eyes,mouth and eyebrow, which are treated as separate units This approach not only achieves expression of a variety of expressions, but also reduces the amount of data storage and reduce the cost of the system greatly.
