说明：  图象压缩技术是用最少的数据量来表示尽可能多的原图象信息的一个过程，这一领域的突破对于通信和多媒体事业的发展 将具有深远的影响．该文介绍了基于MATLAB小渡变换在压缩图象中的应用。并应用MATLAB小波工具箱的相关函数和命令，从 两个不同的方式来实现对此算法的仿真。
(Abstract：The technology of image compression is a process to represent as much origi砌pictorial information as possible with the least amount of image data．The breakthrough in this field will definitely have a far—reaching impact on the development of Communications and multimedia business．This paper first introduces the application of image compression oN the basis ofMATLAB wavelet transformation， and then illustrates the realization of this algorithm simulation from two different ways using some related functiom and commands of MATLAB wavelet toolbox．)
