wave.m

matlab的小波变换源代码 可以用来做图像分析

[X,map]=imread('lina.bmp');
X1=X;
map1=map;
subplot(221);
image(X1);
colormap(map1);
title('lina');
axis square
[X,map]=imread('couple.bmp');
X2=X;
map2=map;
subplot(222);
image(X2);
colormap(map2);
title('couple');
axis square
[c1,s1]=wavedec2(X1,2,'sym4');
sizec1=size(c1);
for i=1:sizec1(2)
    c1(i)=1.2*c1(i);
end
[c2,s2]=wavedec2(X2,2,'sym4');
c=c1+c2;
c=0.5*c;
xx=waverec2(c,s1,'sym4');
subplot(223);
image(xx);
title('融合图象');
axis square
