算术编码，采用了基于上下文的自适应算术编码-Arithmetic coding, context-based adaptive arithmetic coding

通过MATLAB的程序解决相应图上处理中熵值和概率的问题-Adaptive Arithmetic coding. A source generates symbols from alphabet {A, B, C, D}. Probabilities of occurrence of the symbols are initially estimated as: Pr(A)=Pr(B)=0.25, Pr(C)= 0.2, and Pr(D)=0.3. After 100 generate
