Facial animation by reverse morphing on a sequence of real images : application to film and video production

An inverse method of the classical process of morphing, and to match facial animation to a three dimensional facial animation by automatic calculation of the weights of expression models, is presented. The method involves discretizing the real facial animation using a number of characteristic points. The path of each point is followed by optic or magnetic motion capture, or through the filmed images. This tracked down animation is then decomposed. The results of this decomposition are reintroduced into a more complex facial morph which has a totally different topology and geometry.
