In this paper, we propose an deep intensity guidance based compression artifacts reduction model (denoted as DIG-Net) for depth map. The proposed DIG-Net model can learn an end-to-end mapping from the color image and distorted depth map to the uncompressed depth map. To eliminate undesired artifacts such as discontinuities around object boundary, the proposed model is with three branches, which extracts the high frequency information from color image and depth maps as priors. Based on the modified edge preserving loss function, the deep multi-scale guidance information are learned and fused in the model to make the edge of depth map sharper. Experimental results show the effectiveness and superiority of our proposed model compared with the state-of-the-art methods.
