在使用MATLAB完成小波变换程序和通过阈值来压缩图像的过程中，我和许多同学都是边学边用，是从一个接一个的问题中逐步理解小波和MATLAB编写程序的。因此我愿意就个人遇到和解决问题的经验与大家讨论，希望能够对遇到同样问题的人有所帮助。-using MATLAB completed wavelet transform procedures and through the threshold to compress images of the process, I and many of my classmates are used to learn while, is a problem then a gradual understanding of wavelet and MATLAB preparation procedures. Therefore I am willing to personally encounter and the experience to solve the problem with us, it is hoped to have the same problem of some help.
