Complexity scalable control algorithm for intra coding in H.264 under energy constraints
摘要
Abstract
In this paper,the complexity of intra coding is first analyzed so as to achieve a weight of complexity measurement for each intra mode.Then.a new complexity sealable control algorithm for intra coding in H.264 is proposed,based on the rearrangement of the order of candidate modes and an efficient complexity allocation and control(CAAC)scheme at the macroblock(MB)level.The candidate modes of each MB ale rearranged according to the local-edge information.Experimental results show that our proposed algorithm can make an appropriate cut-off point of the candidate modes sequence adaptively according to the current energy condition of a mobile device,so as to adjust the complexity at any level while maximizing the video quality,which can prolong the operational lifetime of the battery with minimum degradation in video quality.关键词
