Abstract :
Ray-space representation is the main approach to realizing free viewpoint television (FTV) with complicated scene. Data compression in ray-space is one of the key technologies in ray-space based FTV systems. In ray-space based FTV system, block matching complication is the most important factor to influence coding efficiency. In this paper, a fast adaptive block matching algorithm is proposed by using starting search point prediction, still block determination and search stop criteria strategies. Experimental results show that the search speed is improved greatly as well as the coding efficiency
