TL;DR
A new 3D hierarchical model of the human face is developed that incorporates a physically-based approximation to facial tissue and a set of anatomically-motivated facial muscle actuators and is efficient enough to produce facial animation at interactive rates on a high-end graphics workstation.
Abstract
Abstract We develop a new 3D hierarchical model of the human face. The model incorporates a physically‐based approximation to facial tissue and a set of anatomically‐motivated facial muscle actuators. Despite its sophistication, the model is efficient enough to produce facial animation at interactive rates on a high‐end graphics workstation. A second contribution of this paper is a technique for estimating muscle contractions from video sequences of human faces performing expressive articulations. These estimates may be input as dynamic control parameters to the face model in order to produce realistic animation. Using an example, we demonstrate that our technique yields sufficiently accurate muscle contraction estimates for the model to reconstruct expressions from dynamic images of faces.
