Abstract： Depth image based rendering (DIBR) is an effective approach for virtual view synthesis in free viewpoint television and 3D video. One of the important steps in DIBR is filling the holes caused by disocclusion regions and wrong depth values. Most of the existing hole-filling methods work well in areas of low spatial activity but fail to obtain satisfactory results in high spatial activity regions. In this paper, we combine the depth based hole-filling and the adaptive recursive interpolation algorithm which is capable of handling edges passing through the missing areas. Accoring to the experimental results, we confirm that the depth based adaptive recursive interpolation algorithm can provide better rendering quality objectively and subjectively.
