Abstract :
Although the animation of virtual clones is no longer just a dream, current drawbacks limit possible applications (contact device, sensor, head immobilization in front of the camera, etc.). In this article, we propose a real-time facial animation analysis/synthesis chain which imposes few constraints. This study has been elaborated for a televirtuality context: several physically distant persons intervene in a common virtual environment via their synthetic representatives. They are thus able to share a virtual community, enter a virtual minitel, follow a visioconference, access telework operations, or even join in multi participant games. The system can be broken down as follows:- Video input
- Real image analysis: extraction of characteristic parameters
- Symbolic interpretation of parameters
- Transfer of these parameters to a remote machine
- Animation of the symbolic or realistic computer graphics clone
- Video output
