哈夫曼编码作为一种最常用无损压缩编码方法,在数据压缩程序中具有非常重要的应用.在此主要对哈夫曼编码算法的原理和基本应用进行了全面的探讨,针对bmp格式图片给出了具体的压缩及解压缩过程及程序.并且结合哈夫曼编码的自身特点对算法进行了研究,提出两种改进方思路,分别为不依赖树结构的规范哈夫曼码压缩算法和基于子块特征的图像压缩算法.实验证明,根据哈夫曼基本,算法代入图例,可算出图例中各像素的哈夫曼编码及其压缩比,约为79%,达到了压缩目的.改进后算法的整个压缩、解压缩过程比传统的哈夫曼压缩算法快得多,所需空间少得多,是一种行之有效的快速压缩算法.

Huffman coding as a lossless compression method most commonly used in data compression process has a very important application. In this main principle of the Huffman coding algorithm and the basic application of a comprehensive discussion is given for the bmp format image compression and decompression of specific processes and procedures.Huffman coding and with its own characteristics of the algorithm was proposed two improved party ideas, were not dependent on the specification tree and the Huffman compression algorithm based on sub-block in image compression algorithms. Experiments show that, according to the basic Huffman algorithm is substituted into the legend, the legend of each pixel can be calculated Huffman coding and compression ratio, about 79% to the compression purpose. The improved algorithm is the compression and decompression processes than the traditional Huffman compression algorithm is much faster, much less space needed is an effective fast compression algorithm.
