“…In 1987, K. Waters introduced a simple parameterized muscle model for facial animation and expression modeling [20]. In 2003, The Duy Bui, in his researches [21] [22], improved Water"s muscle system by adding some parameters for skin wrinkles modeling. In 2008, Marco Fratarcangeli modified Waters muscle system to model facial expressions more naturally [25].…”

In this paper, we developed an automatic system for face ageing and facial expressions modeling using 3D practical faces data. As opposed to previous works, our face ageing system individualized the ageing function based on gender and age groups. Facial expressions are modeled by a muscle system which is improved by our new interpolated formula using characteristic parameters for the structure of each face. Our experiments which were performed on a practical training data set with 3D-face in neutral expression of each person at one age have shown that the effectiveness and efficiency of proposed methods in face ageing and face expressions modeling.

Abstract. In this paper we introduce a method of exporting vector muscles from one 3D face to another for facial animation. Starting from a 3D face with an extended version of Waters' linear muscle system, we transfer the linear muscles to a target 3D face. We also transfer the region division, which is used to increase the performance of the muscle as well as to control the animation. The human involvement is just as simple as selecting the faces which shows the most natural facial expressions in the animator's view. The method allows the transfer of the animation to a new 3D model within a short time. The transferred muscles can then be used to create new animations.
