The origins of the MPEG-4 Facial Animation standard

The MPEG-4 Facial Animation (FA) specification [ISO14496] is the first facial control parametrization to be standardized. In this chapter we place this specification within the context of a broad and detailed FA taxonomy in order to point out its meaning and importance. We discuss the properties of an ideal facial parametrization and measure MPEG-4 against this ideal. Finally, we present a brief history of facial control parametrizations and of the development of the MPEG-4 FA standard.
