An Interactive Facial Animation System.
Fatih Serhat Erol, Uğur Güdükbay · 2001
In this paper, an interactive facial animation system is described. The system is built on top of the facial animation system developed by KeithWaters, which uses a muscle-based face model. We built an interactive facial animation system on top of it to produce keyframe animations of a synthetic face model. The user creates keyframes interactively by either giving prede ned universal expressions to the face (or a meaningful combination of these expressions blended naturally on the face model), or giving expressions to the face by moving the muscle vectors de ned on the face model. The user might alsochange the orientation of the face for a keyframe by rotating it in x- and y-directions. To createintermediate frames, we use cosine interpolation.
