Imagine you have two images of the same size and shape; however, there are differences between the images (like a game of spot 10 different things). MATLAB is the baws:
im = double(imread('input.jpg'))/255;
imsize = size(im);
width = imsize(2)/2;
imdiff = abs(im(:,1:width,:) - im(:,(width+1):end,:));
The output will generate areas of difference.
Math, you’re the bomb!
