New fast depth image-based rendering method for 3DTV

Virtual view rendering is one of the key technologies to realize Three-Dimensional Television (3DTV) system. This paper presents a novel fast method of virtual view rendering that the holes are divided into large and small hole regions, which can be processed according to their size, also we propose using a new way of rendering that some pixels refer to the warping relation of previous frame and the other pixels update the warping relation by re-computing in the current rendering frame, in the process of selecting threshold to determine the two parts of pixel regions, we propose a mathematical model to adaptive select the threshold after a large number of experiments. Experimental results show that the proposed method is effective, and it effectively reduces the rendering time within a certain range of the quality of virtual image declining.
