%X Binarization is an elementary step in the framework of contextbased adaptive binary arithmetic coding.It is introduced to simplify the context modeling and the subsequent arithmetic coding process.In this paper,we propose a novel binarization scheme for arithmetic coding.Based on the observation that the numbers of nonzero coefficients in neighboring blocks are highly correlated,the number of nonzero coefficients of a block is specifically binarized according to the numbers of nonzero coefficients of its top and left neighbors.In addition,a novel mapping rule is designed to map a syntax element to a code number,according to the observed features of probability distribution.Experimental results show that compared to the conventional scheme,this scheme can reduce decoding complexity with comparable coding efficiency.
