The facial expression parameter values are deﬁned by textual descriptions. The expression parameter allows for an efﬁcient means of animating faces. They are high-level animation parameters. A face model designer creates them for each face model. Since they are designed as a complete expression, they allow animating unknown models with high subjective quality [15, 16]. Another beneﬁt of using FAP 2 is that each face model preserves its ‘personality’ such that each face in a group of different face models would show its own version of the facial expression.
They are not independent, and the order in which they are executed is important. There are two high-level controls, phoneme and expression, composed of several lowlevel AMA. Examples of AMA procedures include Close Upper Lip, Right Eyelid, Right Zygomatic, Move Right Eyebrow, Left Lip Raiser, Move Right Eye Horizontal and so on. In 1991, Kalra et al. introduce an approach to FA based on abstraction layers . The central part of this parameterization is the Minimal Perceptible Actions (MPAs).
FACS was not meant for animation, it is rather a system for evaluating (scoring) the facial expressions on the faces of real humans in order to code them in a standardized way comprising a set of 46 Action Units (AUs) or basic facial movements. However, as a result of its systematic approach, foundation on muscle activity and THE BIRTH OF THE STANDARD 11 detailed description of visual effects of each AU, FACS had obvious attractions to the researchers implementing FA systems. Several systems, in particular muscle-based ones, used subsets of FACS as control parameters.
