WAVELET零水印算法

零水印算法，对初学者有帮助的哦，希望大家好好看一下，基于WAVELET的，用matlab实现

function wa=arnold（wwrowkey）
wa=w;
for k=1:key
    for x=1:wrow
        for y=1:wrow
             x1=x+y;
             y1=x+2*y;
             if x1>wrow
                 x1=mod（x1wrow）;
             end
             if y1>wrow
                 y1=mod（y1wrow）;
             end
             if x1==0
                 x1=wrow;
             end
             if y1==0
                 y1=wrow;
             end
             wa（x1y1）=w（xy）;
        end
    end
     w=wa;
end
