Summary:
In this paper, we propose a scheme for multi-view depth map estimation to enhance temporal consistency. After we divide the center image into several segments, we estimate one depth value for each segment using 3-D warping and segment-based matching techniques. In the refinement process, we apply a segment-based belief propagation algorithm. In order to enhance temporal consistency and reliability of the depth map, we define a temporally weighted matching function and apply in the initial depth estimation step. We also apply a temporal postprocessing operation to the refined depth map. Experimental results show that the final depth sequence has improved temporal consistency with reduced errors.
