Low complexity intra mode decision algorithm for 3D-HEVC
Hamza Hamout, Abderrahmane Elyousfi · 2017
The 3D High Efficiency Video Coding (3D-HEVC) has recently been approved by the Joint Collaborative Team on 3D Video coding (JCT-3V) and standardized as an extension of HEVC. To improve the intra coding efficiency of Multi-view Video plus Depth maps (MVD), the 3D-HEVC brings a good intra coding solution, but the computational complexity load increase significantly, which restricts the use of 3D-HEVC encoders in real world application. Therefore, an efficient intra mode decision algorithm is needed. To overcome the aforementioned problem, this paper presents a new mode prediction method enabling high complexity reduction of 3D-HEVC intra coding. The experimental results show that the low complexity intra mode decision algorithm increases the speed of intra coding significantly with negligible loss of encoding efficiency.
