参考视频访问和编码的新功能，这里提出的工作属于与面部和身体动画（FBA）相关的MPEG-4活动的范围。具体来说，我们将展示新的MPEG-4标准如何提供一个适当的框架，虚拟演员动画，手势合成和压缩/传输。有针对性的多媒体服务涉及通过手语为聋人社区提供的低比特率视频电话系统。为了实现上述功能和服务，我们开发并实现了：1）一种符合MPEG-4标准的虚拟人体建模和动画方法，2）目前MPEG-4标准采用的两种压缩技术，3）一种新的方法，用于从视频序列中估计3D姿态的手。
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.
