| description | The video plus depth format, which is composed of the texture video and the depth video, has been widely used for free viewpoint TV. However, the temporal inconsistency is often encountered in the depth video due to the error incurred in the estimation of the depth values. This will inevitably deteriorate the coding efficiency of depth video and the visual quality of synthesized view. To address this problem, a content-adaptive temporal consistency enhancement (CTCE) algorithm for the depth video is proposed in this paper, which consists of two sequential stages: (1) classification of stationary and non-stationary regions based on the texture video, and (2) adaptive temporal consistency filtering on the depth video. The result of the first stage is used to steer the second stage so that the filtering process will be conducted in an adaptive manner. Extensive experimental results have shown that the proposed CTCE algorithm can effectively mitigate the temporal inconsistency in the original depth video and consequently improve the coding efficiency of depth video and the visual quality of synthesized view. |
