This paper presents a filtering approach for semidense probabilistic depth map received from a focused plenoptic camera. In the probabilistic depth map each valid depth pixel contains, beside the depth value itself, a variance which gives a measure for the certainty of the estimated depth. This variance is used in a weighted filtering approach. Here, beside removing outliers and filling holes i...

Depth map upsampling is an approach to increase the spatial resolution of depth maps obtained from ToF (Time of Flight) cameras. Since depth map quality directly affects 3D perception of stereoscopic image, applying different depth upsampling methods to a low resolution depth map causes a variety of perceptions of the stereoscopic images. In this paper, we investigate the relation between objec...

In this paper, we propose a scheme for multiview 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 reliabili...
