Eye Perception Through Tennis

http://www.macroevolution.net/fast-balls.html

Tennis referees are calling balls out when really they are in. Scientists say that there is a slight perceptual error when fast movement is seen by the human eye. This is causing false calls. The video camera shows this. A scientist says that a tennis ball makes an unpredictable change, it bounces, and the brain does a poor job of prediction in this sort of situation.

This is unfair to me but happens in everything. This is not on purpose but causes major problems. I think that in a match they should do a replay when the ball is that close to the line. After this give a signal to the referee to make a correct call. Although it is not the referees fault because of this it still causes crowd problems. If the replay shows the right call then thats what the referee should go with.
