Estimation and animation of faces using facial motion mapping and a 3D face database

![CDATA[Realistic facial animation remains one of the major challenges in computer graphics. The first step in such animation is to acquire a realistic face model. Expensive scanning devices such as laser range finders are convenient for capturing realistic face models. However, as presented by Blanz and Vetter (1999), Blanz et al. (2001), and Hwang et al. (2000), a 3D face database is quite useful for creating models from existing face characteristics in the database. Once a database is established, almost any 3D face can be created from features extracted from photographs.]]
