I have a black and white binary image,i create a copy of this image and i compare these two images using histograms. The result is that these images are exactly the same.
I put a black dot(one pixel) somewhere in the first image an then i compare again the two images and of course the result is that they are not the same anymore.
the question is what can i do to compare two images who are generally the same,but they have very very small differences. Differences that you cant see with naked eyes.
Thank you very much
