A Client Driven Interactive Free-Viewpoint Video System

摘要

A client-oriented free-viewpoint video system is presented in this paper. This system is divided as distinctive but interconnected parts, from video encoder, adaptive and interactive disparity extractor, to virtual view rendering. Adaptive disparity extractor is proposed and embedded to multiview video encoder, and the output bitstream is constructed by disparity layer and video layer. Virtual viewpoint images in the procedure of client-system interaction will be interpolated via disparity based algorithm after the decoded disparity information is refined. Experimental results show that, the bitstream from disparity map accounts for a little proportion in transmission, while high quality of virtual images can be provided to clients.
