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.
