@matrix This is highly suspect. Consider the limited amount of exposed skin on a clothed human. If you averaged out all the pixels of a white person and a black person wearing the same clothing, the small amount of skin shown is not going to swing it that much. Sure humans are good at focusing on and identifying people, but machines are not. They're dealing with color and contrast. Unless this study was performed at a nude beach I call shenanigans. I'd like to know more about how their sensors work.
