One of the major improvements that human vision includes is predictive decoding. Basically, how you interpret an immage is based on your model what you expected that immage to look like. In the case of football, you might build a model of probable footballs for each frame then try to connect them frame by frame until you create a reasonable path and then say ok that's where the actual football is. Then for each new frame you keep extending that path based on what's in the frame and how far the ball can reasonably travel. PS: Classic example, you tend to swap between vase or face, not see them both at the same time. http://en.wikipedia.org/wiki/Rubin_vase http://en.wikipedia.org/wiki/Rubin_vase Or the more striking http://www.michaelbach.de/ot/fcs_hollow-face/index.html http://www.michaelbach.de/ot/fcs_hollow-face/index.html
