MPEG-4 is scheduled to become an International Standard in March 1999. This paper demonstrates an experiment for a virtual cloning method and animation system, which is compatible with the MPEG-4 standard facial object specification. Our method uses orthogonal photos (front and side view) as input and reconstructs the 3D facial model. The method is based on(More)
Human interfaces for computer graphics systems are now evolving towards multi-modal approach. Information gathered using visual, audio and motion capture systems are now becoming increasingly important within user-controlled virtual environments. This paper discusses real-time interaction with virtual world through the visual analysis of human facial(More)
In this paper we describe experiments of real-time facial animation for generation of various virtual actors using high level-actions, compatible with MPEG-4 standard specifications. An MPEG-4 compatible synthetic face and body are integrated into an interactive real-time application allowing the user-friendly control of virtual humans' facial animation and(More)
The continuously increasing complexity of computer an-imations makes it necessary to rely on the knowledge of various experts to cover the different areas of computer graphics and animation. This fact, which can be noted in many areas of scientific working, leads to increasing effort being put into research concerning cooperative working over the internet.(More)
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(More)
