1、 摘 要 随着多媒体技术和通讯技术的不断发展 , 多媒体娱乐、信息高速公路等不断对信息数据的存储和传输提出了更高的要求 , 也给现有的有限带宽以严峻的考验 , 特别是具有庞大数据量的数字图像通信 , 更难以传输和存储 , 极大地制约了图像通信的发展 , 因此图像压缩技术受到了越来越多的关注。图像压缩的目的就是把原来较大的图像用尽量少的字节表示和传输 ,并且要求复原图像有较好的质量。利用图像压缩 , 可以减轻图像存储和传输的负担 , 使图像在网络上实现快速传输和实时处理。 本文主要介绍 数字图像处理的发展概况，图像压缩处理的原理 和特点，对 多种压缩编码方法进行描述和比较 ， 详细讨论了 Huf

3、d bandwidth available to a severe test, especially with large data amount of digital image communication, more difficult to transport and storage, greatly restricted the development of image communication, image compression techniques are therefore more and more attention. The purpose of image compr
4、ession is to exhaust the original image less the larger the bytes and transmission, and requires better quality of reconstructed images. Use of image compression, image storage and transmission can reduce the burden of making the network fast image transfer and real-time processing. This paper mainl
