This is odd

I did the test my self because I'm skeptical. I created a large black background and created large white crossed bars on top of the pattern. Right away I saw the little circles (more of squares because of the size I made it). I used the eyedrop tool to select the section that looks darker and it was the same as the white around it. I don't think the algorithm "falls" for the optical illusion. I don't see how it could anyway because it looks at small sections at a time and compresses it that way. In order to fall for an illusion like this you have to see a significant amount of the picture at the same time. Correct me if I'm wrong please.
