Temporal Consistency Enhancement of Background for Depth Estimation

In this paper, we propose a new scheme to enhance temporal consistency of depth sequences for multi-view depth estimation. When we compute the matching cost for estimating appropriate depth, we add a temporal weighting function to the conventional matching function. Furthermore, since the temporal weighting function only works well for the background, we apply it only to the background. Experimental results showed that the proposed algorithm enhanced the temporal consistency for the background of the depth sequence and reduced flickering artifacts in the virtual view while maintaining visual quality.
