中文说明：小波指的是一种能量在时域非常集中的波，它的能量有限，都集中在某一点附近，而且积分的值为零，这说明它与傅里叶波一样是正交波,一维的小波变换延伸到二维，可以应用到图像的变换，压缩包里有关图像变换的M文件，自带丽娜图片，也可以自己另外在设置别的图像，
English Description：
Wavelet refers to a kind of wave whose energy is very concentrated in the time domain. Its energy is limited, and it is concentrated near a certain point, and the integral value is zero, which indicates that it is an orthogonal wave like Fourier wave, The one-dimensional wavelet transform extends to two-dimensional, and can be applied to image transformation. The m file about image transformation in the compression package, with Lina image, can also set other images,
