Abstract :
We describe the components of the system used for real-time facial communication using a cloned head. We begin with describing the automatic face cloning using two orthogonal photographs of a person. The steps in this process are the face model matching and texture generation. After an introduction to the MPEG-4 parameters that we are using, we proceed with the explanation of the facial feature tracking using a video camera. The technique requires an initialization step and is further divided into mouth and eye tracking. These steps are explained in detail. We then explain the speech processing techniques used for real-time phoneme extraction and subsequent speech animation module. We conclude with the results and comments on the integration of the modules towards a complete system
