说明：  WAVELET BASED COMPRESSION，本程序用matlab工具编程实现了小波变换进行图像压缩，并且显示压缩前后的图像。代码很简明清晰，适合初学者研究和学习。
(WAVELET BASED CPSV, the procedures used Matlab programming tools of wavelet transform for image compression, and compression shown before and after images. Code is simple clear and suitable for beginners to study and emulate.)
