摘要

Aiming at fully exploiting the temporal and spatial redundancy and answering the "Call for Proposals" for multi-view video coding (MVC) issued by MPEG, a MVC scheme based on vector field estimation and weighted disparity interpolation is presented. By extending the loop constraint to multi-view images for a parallel camera model and proposing the novel "vector field estimation" scheme, the temporal and spatial redundancy is significantly reduced. Also, weighted disparity interpolation is performed to predict adjacent disparity vectors. Experimental results over multi-view image sets imply that the coding efficiency is improved about 0.2-0.5 dB compared with previous coding approaches such as H.264/AVC simulcast and JMVM.
