Bézier volume deformation model for facial animation and video tracking

Abstract

Capturing real motions from video sequences is a powerful approach to automatically build facial deformation model. In this paper, a 3D Bézier volume deformation model is proposed for both synthesis and analysis of facial movements. Since this model is independent of the mesh structure provided the feature points are given, it is capable of animating geometric facial models of different shapes and structures. Of the same importance, the linear property of this model implies a simple and robust analysis algorithm, from which a customized facial deformation model is derived. Experimental results on animation and video analysis are demonstrated in this paper.
