Liptracking and MPEG4 Animation with Feedback Control

This article deals with facial segmentation and liptracking with feedback control by face model synthesis. On this topic, the search community is divided into two parts : analysis and synthesis.We want to use all the knowledge to create a global analysis/synthesis chain where the image analysis needs the 3D synthesis and conversely. As it happens, applications like face tracking or augmented reality need a rapid, robust and descriptive-enough solution. Our solution is based on a two step approach : the first step is a real-time facial segmentation with active contour models and the second step recovers a 3D-face model in order to extract more precise parameters to adjust the first step. The contribution of this paper is to couple two research fields for creating a real time application. The results obtained show rapid and robust performances which could be exploited in a more global real-time face tracking application.
