Modeling of facial emotion expressions (facial mimics) is essential to many application such as medicine, computer graphics and animation. Especially in craniofacial surgery, the realistic prediction of patient’s dynamic appearance is an important additional criterion for the evaluation of the surgical planning. For a realistic simulation of individual facial mimics, an adequate biomechanical model of soft tissue including the mimic musculature is needed. In this paper, we present our approach for the estimation of individual facial mimics on the basis of geometrical models of human anatomy derived from tomographic data and the finite element modeling of tissue biomechanics.
