Abstract :
We describe an approach to synthesizing human expressions based on 3D face model and the facial motion parameters obtained by tracking the model vertices in real expression sequences. The synthetic sequences of different expressions can be generated by deforming the face model using these motion parameters. This method can be used to effectively compress video sequences where the human faces are dominant, such as video phones and teleconferences
