Sažetak
The ACTS project VIDAS (Video Assisted with Audio Coding and Representation) deals in a large part with obtaining a very low bitrate video conferencing system by employing facial analysis and synthesis techniques. The general idea is to use the image analysis techniques to extract the facial anatomy and then track the face motion. This data is efficiently compressed for network transmission, then used at the receiving side to generate the synthetic talking head. Here the face synthesis is used. For the efficient transmission it is desirable to be standardized, and one of the very important goals of the project is to participate and actively contribute to the Facial Animation part of the MPEG-4 standard. The Swiss partners of VIDAS – University of Geneva and EPFL are involved in the facial synthesis part of the project, and also have a major involvement in the MPEG-4 standard – Facial Animation part. In this paper we describe our technical contributions within the VIDAS project and our contribution to the MPEG-4 standard.
