摘要
实现了经典算术编码的流程设计,提出基于上下文自适应算术编码的算法。建立了基于上下文的多阶自适应的概率模型,使其符号的压缩码长尽量的接近其熵值。
The paper realizes the flow chart design of traditional arithmetic coding, and introduces an adaptive binary arithmetic coding algorithm based on multi-order context.Then the paper also builds multi-order context adaptive probability model, which enables the shortened coded character almost approach its entropy rate.
