Temporal pixel classification and smoothing for higher depth vid...

Multi-view view plus depth (MVD) is an effective scheme for representing 3D scenes. However, weak temporal correlation of depth video, caused by inaccuracy depth estimation and capture, seriously decreases its compression ratio and deteriorates the video quality of rendered virtual views. This paper proposes a depth video preprocessing algorithm to obtain high depth video compression performance. Firstly, depth video and its associated texture video in common temporal-spatial domain (CTSD) are t
