Analysis of the Encoding Efficiency of 3D HEVC

Abstract

Abstr act This paper mainly studies currently developing 3D video coding based on HEVC. HEVC-based 3D video coding mainly focuses on 3DTV and autostereoscopic video compression system. A variety of new encoding tools, such as inter-view motion prediction and depth modeling modes, have been added in 3D HEVC. The interest is created to confirm if these new features and tools improve the encoding efficiency of 3D HEVC. The goal of this article is to analyze the encoding and compression efficiency of 3D High Efficiency Video Coding. In our experiments for stereo video without depth maps, 3D HEVC provides 59.44% and 24.32% average bit rate savings with respect to HEVC simulcast for the dependent view and both two views, while MVC provides 12.53% and 5.99% in comparison with H.264/AVC simulcast. The results indicate that 3D HEVC can remove redundancy between the views more effectively than MVC.

Fast three‐dimensional video coding encoding algorithms based on edge information of depth map

“…In (13), Time tp and Time to represent the computation time in the whole coding process of the proposed algorithm and the original 3D-HEVC software, respectively. In (14), Time pre denotes the preprocessing time of the proposed algorithm. Table 1 in Section 3.2 shows the coding performance of the fast CU partitioning method enabled and disabled for I slice, respectively.…”

“…However, H.264/AVC is still insufficient for compressing high‐resolution video [7, 8]. Therefore the high‐efficiency video coding (HEVC) standard [9–14] was thus developed by the joint collaborative team on video coding, which was jointly established by MPEG and VCEG.…”
