ABSTRACT
Video depth reconstruction is a long-term problem in computer vision. A fair amount of previous work adopts Markov random field model in depth estimation formulation. Various local prior terms are included into global smoothness of those optimization frameworks. However, the estimated depth discontinuities are usually not consistent with object boundaries and intra-object smoothing is not well achieved. Such problems are addressed in color segment-based methods but cannot be solved well when color segments exist across object boundaries or are not temporarily consistent.

Fast frame-rate up-conversion of depth video via video coding
MM '11: Proceedings of the 19th ACM international conference on MultimediaRecent development of depth sensors has facilitated the progress of 2D-plus-depth methods for 3D video representation, for which frame-rate up-conversion (FRUC) of depth video is a critical step. However, due to the computational cost of state-of-the-...
Consistent Depth Maps Recovery from a Video Sequence
This paper presents a novel method for recovering consistent depth maps from a video sequence. We propose a bundle optimization framework to address the major difficulties in stereo reconstruction, such as dealing with image noise, occlusions, and ...
Consistent video depth estimation
We present an algorithm for reconstructing dense, geometrically consistent depth for all pixels in a monocular video. We leverage a conventional structure-from-motion reconstruction to establish geometric constraints on pixels in the video. Unlike the ...
