Improved prediction structure for multi-view video coding

Multi-view Video Coding(MVC)is a research hotspot in the video coding.In order to reduce the computational complexity and improve the temporal random access as well as spatial random access performance of hierarchical B pictures coding structure used as the basic structure in Joint Multi-view Video Coding(JMVC),an improved prediction structure is proposed.The frame in B-view which uses the immediate previous frame as its reference adopts only temporal prediction,and inter-view prediction is skipped in non-anchor frames in P-view skip inter-view prediction,so that computational complexity is reduced and random access ability is im-proved.The position of I-view is also studied to minimize the loss of coding efficiency introduced.Experimental results have shown that compared to the hierarchical B pictures coding structure in JMVC,the proposed scheme achieves a remarkable reduction of encoding time on average with insignificant gain loss.Better random access performance has also been obtained.
