This paper addresses the issue of lip tracking and cloning using appearance models. In this perspective, a statistical color-based lip detector is first used to classify the pixels of an image into lip and non-lip pixels. This rough estimation of the lip position is then used to initialize an appearance model. This models convergence allows to refine the positions of the MPEG-4 compatible feature points placed around the lip contours. The optimal position of the feature points is then used as a… CONTINUE READING
