摘要

本文描述了Cohen和Massaro(1993)提出的协同衔接模型的修改版本。利用ELITE光电系统获取的真实电影数据，采用半自动最小化技术训练模型的动态特性。最后，将该模型成功应用于意大利说话头GRETA，并通过实例说明了所得到的动画技术的自然性。

Labial coarticulation modeling for realistic facial animation

A modified version of the coarticulation model proposed by Cohen and Massaro (1993) is described. A semi-automatic minimization technique, working on real cinematic data, acquired by the ELITE opto-electronic system, was used to train the dynamic characteristics of the model. Finally, the model was applied with success to GRETA, an Italian talking head, and examples are illustrated to show the naturalness of the resulting animation technique.
