Abstract

In the current internet based applications, 3D video encoding needs the service quality improvement and transmission priority control for collaboration purpose. In the 3D video system, the capture stage provides the texture and depth images for encoding. In many scenario cases, the foreground moving objects need to be detected, quantized with refined step and transmitted with high priority. The distributed multimedia plays (DMP) provide the real time, near-natural size, collaboration, stereoscopic and multi-view experience. A novel collaboration-oriented 3D video encoding approach is presented in this paper for DMP, in which the integration calculus is introduced. Also, this approach is hardware oriented and friendly. Its process is in pipeline and parallel with other function modules in DMP system. The foreground objects with performing behavior could be detected efficiently and robustly. Their encoding quality and transmission priority level could be guaranteed accordingly. Experiments show this approach is global image processed and robust in the DMP application. Also, it is helpful for improving the quality of encoding and the depth image base rendering (DIBR) for 3D effect.
