Application of computer vision in Cricket: Foot overstep no-ball detection

Cricket is a worldwide popular game where different technologies are being used to help the match umpires to make decisions. Often due to the human perception, deciding whether a bowled delivery is a no-ball or legal ball which causes controversy. As only a single ball can change the fate of the game, so it is obvious to make accurate decision regarding no ball. In this paper, we have divided the bowling crease into two regions and applied image subtraction method on both regions to find the change in pixel values. Later, we have applied our proposed method on real world video frames. Since our proposed method to detect the overstep no ball is grounded on pixel by pixel image subtraction, it eliminates the inadequacy of human perception.
