我们不是捕捉特定的表演，而是使用捕捉数据来生成复杂的面部动画设置，然后可以使用该设置来制作全新的合成表演的动画。作为面部设置的基础，演员的动作被捕捉，以执行符合 Paul Ekman 的面部动作编码系统 (FACS) 的全套面部动作。跟踪的特征点包含非线性动画曲线，这些曲线组合起来精确地描述了每个动作单元表演期间面部所有区域的运动。运动捕捉数据经过清理、标准化并与全局头部运动分离。
Rather than capturing a specific performance we use capture-data for generating a sophisticated facial animation setup which may then be used to animate entirely new synthetic performances. As a basis for the facial setup an actor is motion captured performing a full set of facial movements conforming to Paul Ekman’s Facial Action Coding System (FACS). The tracked feature points contain nonlinear animation curves which in combination precisely describe the motion in all regions of the face during each Action Unit performance. The motion capture data is cleaned, normalized and separated from the global head movement.
