MPEG4 parameterization for facial deformation

In 3D scenes, which put in scene virtual characters, realism is very important. The facial animation is one of its key points. This is principally due to the following reasons: the face and the many muscles which it is composed can generate a multitude of expressions; the complexity of this area is reflected in the existing approaches in that it is very difficult to create quality entertainment without a long and fastidious manual work. In this paper, we focus on facial deformation, especially to the animation synthesis that can generate facial expressions, based on the MPEG-4 standard parameterization. We implemented a method for animation´s generation, which is the deformation of mesh using a method based on control points. Our input is the mesh of a 3D face for an animated face. We are interested in defining control points and their areas of influence; we presented a method that computes automatically the areas of influence of each control point, to reduce manual intervention.
