Fuzzy Connections in realistic real-time facial animation

Abstract

Real-time realistic reproduction of facial expressions has the potentiality to become a fundamental tool for rehabilitation in psychological and psychiatric disorders. The most accurate techniques are based on biomechanical modelling the face. However, they are inapplicable when real-time is required due to the computational load. An alternative solution pursued here, is to first capture the facial surface by a three-dimensional scanner, and then apply to it the motion of few repere points captured live. In particular, we have implemented a two-layered model, where the connection between the lower layer (control mesh) and the upper layer (topologial model) is realised by fuzzy-connections. This avoids cracks over the surface and gives a smooth deformation of the face.
