So there ’ s a great correlation among the second bitplane . so we offered a new arithmetic coding scheme in which the design of context models is based on level and bitplane . considering the difference between luma and chroma coefficients , we will make it separately 由于abslevel = 1的高概率出现,使得第二位平面具有很大的相关性,因此文中算术编码的上下文模型的设计方案主要基于level值和bitplane 。

This paper presents a algorithm that combined unary code and exp - golomb code . it switched separately in consideration of the difference between luma and chroma coefficients , instead of setting a marking bit which will bing loss at the same time , and also added some corresponding context models . it had been tested on sd , hd and cif , three types of sequence , and the bitrate had been saved by 1 . 24134 % , 0 . 10016 % and 0 . 16029 % on average 针对这种情况,本文引入exp - golomb码来减少较大的变换系数二值化的冗余问题,提出了一种unary码和exp - golomb码相结合的的二进制化算法,该算法避免了设立标志位所带来的附加损耗,分别针对于变换系数中的luma系数和chroma系数的概率分布特点,采取了不同的自适应切换设置,并且相应地增加了概率模型。
