code,dictionary

A kind of series data compression system is presented that is made up of the predictive coding and the dictionary coding method, accomplished with C++ Builder.

采用字典编码与预测编码串联的方式组成了数据压缩系统 ,并用 C++Builder语言实现了该系统 。

This paper describes the basic principle of dictionary encoding and Huffman encoding which are widely used in losslesscompression.

本文从字典编码和霍夫曼编码的基本原理出发,分析了二者在目前比较常用的无失真压缩编码技术中的应用,重点介绍了具有代表性的LZSS算法与霍夫曼编码的综合应用,并概述了其译码实现过程。
