说明：  图象处理中经常用的小波分析matlab程序(Image processing are often used in wavelet analysis matlab program)

Multisim - Band Pass Filter

f=zeros(30,30) f(5:24,13:17)=1 imshow(f, notruesize ) F=fft2(f,256,256) F2=fftshift(F) figure,imshow(log(abs(F2)),[-1 5], notruesize )

对含窄带噪声的语音信号进行小波去噪，并汇出LP谱和MVDR谱(LP and MVDR based wavelet)

去雾算法，包括了matlab代码，和几个可以使用的exe文件(Defogging algorithm)

对信号进行四级小波包分解重构的源程序。将要分解的数据文件存放在E: a.wav (4 of the signal reconstruction wavelet packet decomposition of the source. Decomposition will be stored in the data file E: ta.wav ' )

用MATLAB编写的混沌序列图像加密程序，密钥可以从0到1之间的任何一个数，加密密钥跟解密密钥一样才能正确解密.rar(Chaotic sequence using MATLAB image encryption program, the key can be from 0 to 1 between any number of encryption keys with the correct decryption key to decrypt the same. Rar)
