Abstract
This paper presents a model to generate personalized facial animations for avatars using Performance Driven Animation (PDA). This approach allows the users to reflect their face expressions in his/her avatar, considering as input a small set of feature points provided by Computer Vision (CV) tracking algorithms. The model is based on the MPEG-4 Facial Animation standard, and uses a hierarchy of the animation parameters to provide animation of face regions where it lacks CV data. To deform the face, we use two skin mesh deformation methods, which are computationally cheap and provide avatar animation in real time. We performed an evaluation with subjects in order to qualitatively evaluate our method. Results show that the proposed model can generate coherent and visually satisfactory animations.
