Question

Hi, I am the beginer for doing simple image subtration to obtain defect image. Is it possible to make it only show the defect image if nothing difference wont show? clc   clear   close all   warning off;   x=imread('origin.jpg');   y=imread('capture.jpg');   [g, c, d]=size(x);   y=imresize(y,[g,c]);   subplot(1,3,1);   imshow(x);   title('origin image');   subplot(1,3,2);   imshow(y);   title('capture image');   subplot(1,3,3);   imshow(x-y);   title('defect occur if difference colour shown');

may be add some judge rule?such as
clc
clear
close all
warning off;
x=imread('origin.jpg');
y=imread('capture.jpg');
[g, c, d]=size(x);
y=imresize(y,[g,c]);
subplot(1,3,1);
imshow(x);
title('origin image');
subplot(1,3,2);
imshow(y);
title('capture image');
bw = find((x-y) > 1);
if numel(bw) > 1
    subplot(1,3,3);
    imshow(x-y);
    title('defect occur if difference colour shown');
end
