Abstract
This paper discusses object modeling, coding, and trasismission for multimedia communications in the desktop environment. To reduce video quality degradation caused by coding distortion and networking errors, we consider the compression and transmission of multi-media signals in a joint Fashion, First, a three-level signal representation model is developed to connect 3-D graphics with video pixel information through 2-D object shapes. Second, nonrigid facial motion is modeled and is used to synthesize video images. Turd, the video coding rates are adapted based on feedback of the network states and receivers.
