Abstract
Virtual view rendering is one of the key technologies to realize three-dimensional television (3DTV). Because of the depth value's discontinuity in the depth map, there are lots of holes in the rendered virtual view image. To solve this problem, depth map pre-processing methods are proposed and analyzed in this paper. The number of holes resulted from 3D warping is counted, and the virtual view images obtained from different reference views are fused. Finally, the number of holes in the fused virtual view image is also counted, and the quality of virtual view image is evaluated to measure the effect of depth map pre-processing. Experimental results show that the proposed pre-processing method can effectively reduce the number of holes and improve the quality of rendered virtual view image.
