Wavelet-image-denoising-procedures
- 小波图像去噪程序。th=sigma*sqrt(2*log10(L*T)) 计算阈值 ch=c(1,num(4-i,1):num(4-i,3)+step(4-i)-1) 对各高频系数进行阈值处理 chl=length(ch) for j=1:chl if abs(ch(j))>=th ch(j)=sign(ch(j))*(abs(ch(j))-2*th/(1+exp(m*(ch(j)^2)))) 阈值处理函数 else -Wavelet image denois
OneDimensionalDiscreteWaveletTransforms
- 本实验要求开发一个基本的哈尔小波变换程序包,用于后续的实验。实验中使用哈尔基函数特有的“平均”与“差分”方法。首先要编写一个计算哈尔小波的j-尺度离散小波变换程序。并且要编写一个计算哈尔小波的j-尺度的逆离散小波程序,并用课本上的例7.8来验证所编写的程序-The experiment calls for the development of a basic package Haar wavelet transform for the follow-up experiment. Harki fu

DCT
- 这段程序是,J(p,q)代表的二值水印图像,二值水印图像的像素值只有0和1,所以if J(p,q)==0,a=-1 ,是如果水印图像像素值是0的话,让a=-1,当水印像素值为1的话,让a=1,我个人认为是为了提取时候好提取-DCT digital watermark embedding and extraction of
