说明：  基于Matlab的数字图像相关法的程序实现，本文简单介绍了基于小波变换的图像分解和重构，在此基础上讨论了Matlab语言环境下图像压缩和图像融合的基本方法。
(Matlab-based digital image correlation method of the program, this article briefly introduce the wavelet-based image decomposition and reconstruction, on the basis of discussion under the Matlab language environment image compression and image fusion of the basic method.)
