LOW COMPLEXITY ALGORITHM FOR INTER-LAYER PREDICTION OF H.264/SVC

摘要

Inter-layer prediction of H.264/SVC can help to improve the coding efficiency with increased computation complexity. This paper presents a low complexity algorithm for inter-layer prediction. The proposed algorithm focuses on the reduction of the candidate modes by making use of the correlations of the encoding cost between the base layer and enhancement layers. For macroblocks with the collocated macroblock coded by INTRA or INTER type two algorithms are proposed, respectively. Both algorithms efficiently decrease the redundant candidate modes by estimating from the base layer coding information. The experiment results show that the proposed algorithm can significantly reduce redundant computation complexity with almost no coding efficiency loss.
