FAST INTER MODE PREDICTIONS FOR SHVC

Résumé

The Scalable High Efficiency Video Coding (SHVC) has very high coding efficiency, but its computational complexity is also very high. This definitely limits its wide applications, particularly for real-time video applications. Therefore, it is crucial to improve the coding speed. In this research, we have proposed a new inter mode prediction algorithm for quality SHVC, in order to improve the coding speed while maintaining coding efficiency. First, we divide mode prediction into square mode prediction and non-square mode prediction. Second, in the square mode prediction, Inter-Layer Reference (ILR) and merge modes are predicted based on depth correlation. Moreover, ILR mode, merge mode and inter 2Nx2N are early terminated based on Rate Distortion (RD) cost. Third, if the early termination condition cannot be satisfied, non-square modes are further predicted based on the distribution of residual coefficients. Experimental results have demonstrated that the proposed algorithm can significantly improve the coding speed with negligible coding efficiency loss.
