Hello,

In order to find the intersection of two similar image,

you can do image subtraction.

clear; clc;
I = double(imread('cameraman.tif'));
J = double(I);
J(115:155, 192:204) = 50;
intersection = abs(J - I);
imshow(uint8(I)); title('Image A');
figure, imshow(uint8(J)); title('Image B');
figure, imshow(uint8(intersection)); title('Intersection A and B');

Hello,

Sorry for waiting.

Here the code :

array = uint8(intersection);
for row = size(intersection,1) : -1 : 1
    if ~any(find(intersection(row,:)))       
        array(row,:) = [];
    end
end
for col = size(intersection,2) : -1 : 1
    if ~any(find(intersection(:,col)))    
        array(:,col) = [];
    end
end
imshow(array);

MATLAB: Convert matrix of RGB double values to image

I just realized the following works, but please let me know if I am losing information by converting to uint8,

figure;
imshow(uint8(rgbMatrix*255)); % RGB images should be in the 0-255 range, not 0-1
