Referring to the new functionality of video access and coding, the work presented here lies within the scope of MPEG-4 activities related to Face and Body Animation (FBA). Specifically, we show how the new MPEG-4 standard offers an appropriate framework for virtual actor animation, gesture synthesis and compression/transmission. The targeted multimedia service concerns a low bit rate video-phone system for the deaf people community by means of sign language. To address the above-mentioned functionalities and service, we have developed and implemented: 1) a virtual human body modeling and animation method which is MPEG-4 compliant, 2) two compression techniques currently adopted by the MPEG-4 standard, 3) a novel method for estimating the 3D pose of the hand from video sequences.
