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');

Possibly you are looking for this information: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

You will need to say more about what you mean by finding the intersection region. Are you trying to do something like build a panorama image? If so then that is more difficult than one might think at first, as one has to correct for different densities of information as you get further from the optical axis, and then one has to do image registration with the corrected images.
