| Abstract: | Basic principle and implementation of adaptive arithmetic coding is discussed in this paper,a lossless image coding algorithm is also presented,which is based on prediction coding as well as adaptive arithmetic coding.This method can choose one proper coding model according to the context of image to achieve higher coding efficiency.Simu-lation results show that this kind of method can greatly improve the performance of lossless image coding. |
