基于区域大小自适应的Huffman压缩技术

Size Adaptive Region Based Huffman Compression Technique

Utpal Nandi, Jyotsna Kumar Mandal

摘要:

本文提出了一种无损压缩技术,它采用变长区域形成技术将输入文件分成若干变长区域。在形成区域之后,针对整个文件获得霍夫曼码。每个区域的符号被逐个压缩。并与基于区域的Huffman压缩技术和经典Huffman压缩技术进行了比较。所提出的技术提供了更好的压缩比为某些文件比其他两个。

英文摘要:

A loss-less compression technique is proposed which uses a variable length Region formation technique to divide the input file into a number of variable length regions. Huffman codes are obtained for entire file after formation of regions. Symbols of each region are compressed one by one. Comparisons are made among proposed technique, Region Based Huffman compression technique and classical Huffman technique. The proposed technique offers better compression ratio for some files than other two.
