Description
Summary:Depth edge preservation is important for improving synthesized view quality in depth map coding. A joint texture/depth edge-directed up-sampling algorithm for depth map coding is proposed in this paper. The depth up-sampling algorithm takes into account the edge similarity between depth map and corresponding texture image, and structural similarity between low resolution depth map and high resolution depth map. Based on the these characters, the optimal MMSE up sampling coefficients are estimated from the local covariance coefficients of down-sampled depth map and corresponding texture image. Experimental results show that the proposed up-sampling algorithm for depth map coding improves both depth map coding efficiency and synthesized view quality.
