Facial Deformations for MPEG-4

Facial Deformations for MPEG-4
The new MPEG-4 standard, scheduled to become an International Standard in February 1999, will include support not only for natural video and audio, but also for synthetic graphics and sounds. In particular, representation of human faces and bodies will be supported. In the current draft specification of the standard [MPEG-N1901, MPEGN1902] Facial Animation Parameters (FAPs) and Facial Definition Parameters (FDPs) are defined. FAPs are used to control facial animation at extremely low bitrates (approx. 2 kbit/sec). FDPs are used to define the shape of the face by deforming a generic facial model, or by supplying a substitute model. We present algorithms to interpret the part of FDPs dealing with the deformation of a generic facial model, leading to a personalisation of the model. The implementation starts from a generic model, which is deformed in order to fit the input parameters. The input parameters must include the facial feature points, and may optionally include texture coordinat...
