摘要
新发布的3D-HEVC由于其基于高效视频编码(high efficiency Video Coding, HEVC)的高压缩效率而获得了显著的反响。然而,由于引入了编码单元(CU)大小决定过程和率失真优化(RDO)过程,其编码过程的复杂性也很大。本文提出了一种充分利用访谈相关性的快速编码算法。通过视图间相关统计分析,可以从独立视图中预测依赖视图的候选CU深度,而不是通过蛮力RDO过程来确定CU深度。实验结果表明,该方法可节省51%的纹理编码时间,且纹理编码损失可以忽略不计。
A fast coding algorithm based on inter-view correlations for 3D-HEVC
The newly published 3D-HEVC has received a remarkable response due to its high compression efficiency which is based on High Efficiency Video Coding (HEVC). However, the complexity of its encoding process is also large as a result of introducing the coding units (CU) size decision process together with the rate distortion optimization (RDO) process. In this paper, a fast coding algorithm making good use of the interview correlations is proposed. With the inter-view correlation statistical analysis, the CU depth candidates of the dependent views can be predicted from the independent view instead of the brute force RDO process in determining CU depth. The experimental results show that the proposed method saves 51% time in texture coding and the loss is negligible.
