Motion and Structure Information Based Adaptive Weighted Depth Video Estimation
This paper presents a novel depth video estimation method, which improves estimation property and refines the temporal consistency and spatial accuracy at the same time. The main idea is to incorporate more useful motion and structure information into depth estimation. First, an adaptive weight is calculated based on the motion information of adjacent frames and attached to a temporal term to update the energy function, thus reducing the matching errors and improving temporal consistency. Second, the depth continuity/discontinuity in spatial domain is properly judged by combining the edges of initial depth map and color segmentation, and used in the refinement strategy. Finally, we evaluate the performance of our algorithm with several public stereoscopic video sequences. Experimental results show that the qualities of depth video and synthesized virtual view are all improved.
