数学建模常用算法的MATLAB程序,在全国数学建模比赛中能使用!(MATLAB OF MATHMATIC,SOME EXAMPLE YOU CAN USE)

这是一个小波去噪的程序，除了实现了最经典的图像去噪算法外，还使用了最新的带有方向性的小波，去噪效果非常好(This is a wavelet denoising procedure, in addition to realize the most classical image denoising algorithms, but also uses the latest with a directional wavelet, denoising effect is very good)

It is mainly used for fingerprint recognition in matlab
