基于多参数的数据压缩算法
A Lossless Compression Algorithm Based on Multi-parameter
摘要
Abstract
According to the study and analysis of Huffman coding method, propose a kind of lossless compression algorithm which is based on multi-parameter. Through sort and statistical for the number of original data,then merge them to meet the requirement of best Huffman encoding,thereby generating a data merging table which occupies less space,and encode the original data which is divided to one-unit code ( prefix code) and distinction code ( suffix code) . The start point of the data merging is the multi-parameter in this re-search. The original data can be determined by using these parameter. There is no need to bit by bit matching or generating encoding table when decoding. Compared with the original method,the lossless compression algorithm which is based on multi-parameter has simple coding structure and operating. It has higher efficiency in both coding and decoding.关键词
