Virtual view synthesis and image comprehension have become easier with the aid of depth information. However, when a depth image is compressed, severe distortions along boundaries may occur, thus leading to performance degradation. To solve this problem, we propose in this paper a two-stage filtering that consists of binary segmentation-based depth filtering and the reconstruction using a Markov Random...
In the general 3D scene, the correlation of depth image and corresponding color image exists, so many filtering methods have been proposed to improve the quality of depth images according to this correlation. Unlike the conventional methods, in this paper both depth and color information can be jointly employed to improve the quality of compressed depth image by the way of iterative guidance. Firstly,...
