| Popis: | 3D-high efficiency video coding (3D-HEVC) is the latest new extension standard of high efficiency video coding (HEVC) for multi-view video plus depth (MVD). Several novel coding tools are employed in the 3D-HEVC for better representation of the dependent texture and depth video. However, employing these tools causes a significant increase in coding complexity. In this paper, we introduce a fast coding scheme for complexity reduction of 3D-HEVC. Since the multi-view video and depth are highly content dependent, testing all the prediction modes are not efficient. A statistically analysis is performed to study the features of 3D video contents from spatio, spatial and inter-view correlations. Based on this correlation, the proposed fast coding scheme determines to skip some treeblocks of texture and depth video at the early stage. Experimental results demonstrate that the proposed scheme can save 63.3% runtime of 3D-HEVC with only 0.41% bitrate increase. |
