Abstract

Scalable High Efficiency Video Coding (SHVC) provides high compression efficiency at the expense of considerable computational complexity. In this paper, a fast algorithm is proposed to reduce the computational complexity of SHVC intra coding. The coding depth information, texture complexity, and spatio-temporal correlation are jointly used to achieve a faster depth decision process. The mode dependency between the base layer and the enhancement layer is combined with the temporal correlation to simplify the mode decision process. Experimental results demonstrate that the proposed scheme saves encoding time by up to 59% compared with the SHM12.0 encoder with negligible degradation in Rate Distortion (RD).
