2D Trajectory-based Position Estimation and Tracking of the Ball in a Basketball Video
Bodhisattwa Chakraborty, Sukadev Meher · 2011
In this paper, the problem of ball detection-and-tracking in a real time video is addressed. The presence of many moving objects in the background in a sports video makes ball detection a very difficult job. Added to this, the ball-images are also get deformed due to the high speed movement of the ball. It is very difficult to correctly detect and track a ball directly in a sports video. In this paper, a trajectory based ball-detection-and-tracking method is proposed. Using the trajectory information the ball locations are estimated and finally the ball is efficiently tracked along the trajectory.
