这么代码是用Matlab编写的

clear all;

Ximage=double(imread('e:\work\Lena.jpg'));%待隐藏图像
n=2;
times=2;
% key0=0.1;
key(0)=0.1;???????
M=Size(Ximage,1);
N=size(Ximage,2);
figure(1)
imshow(Xiamge,[]);

% for(i=1:M*N*n)
    for(j=1:M*N*n)
        key1(j)=1-x*key1(j-1);
    end
    key2=key1;
    for(j=1:M*N*n)
        key2(j)=abs(key2(j-1)*255);
    end
    for(j=1:M*N*n)
        Z(j)=Key1(j)&Key2(j);
    end
% end
figure(2)
Imshow(Z,[]);
