matlab有相应的函数，可以直接调用。close allclear allclc;I=imread('F:\图像变化检测\image\Texture image(3.27)\texture5.tif');%I=rgb2gray(I);
%% if the input image is RGB form.%I=I(1:128,1:128); %% derive a small one just for demoI=im2double(I);w=15;I1=wextend('2D','sym',I,(w-1)/2); %I=wextend('2D','sys',I,[w/2-1/2,w/2-1/2])... |
