【摘要】 面向动画创作的三维人脸表情动画生成框架由人脸模型简化、特征点驱动以及表情动画生成等三部分组成。以MPEG-4人脸动画定义标准为基础,提出了以脸部定义参数流驱动关键特征点的动画生成算法。实验结果表明:该方法实现了真实感和实时性的有效结合,能满足动画创作的要求。更多还原

【Abstract】 3D human facial expression animation is an import research area in computer graphics.This paper proposes a 3D facial expression animation framework.It consists of the human face model simplification,feature point driving and facial expression animation.A facial feature point driving algorithm using the FAP stream is proposed based on MPEG facial animation definition.Experiments prove that the proposed method realizes a tradeoff between the real-time and the reality,thus satisfying the requirements of the animation design.更多还原
