| Abstract: | This article deals with facial segmentation and liptracking with feedback control for real-time animation of a synthetic 3D face model. Classical approaches consist in two successive steps: video analysis then synthesis. Our approach departs from them in that we build a global analysis/synthesis processing loop, where the image analysis needs the 3D synthesis and conversely. A first facial segmentation is computed according to which the 3D face model is positionned. Then the feedback loop, implemented from the 3D animated model into the input pixel segmentation algorithm, helps to correct some (few) bad segmentation points, detected by measuring the distance between lip contour points and corresponding 3D face model points. | ||
