Title: OBJECT TRACKING USING OBJECT SPEED INFORMATION
Abstract:
Embodiments herein include a method for tracking objects in a sensing region that includes determining a first position of a first object and a first position of a second object in the sensing region. The method includes determining that one of the objects has left the sensing region and one of the objects has remained in the sensing region at a current position. The method includes calculating a speed of each of the first object and the second object based on a difference in position of each respective object in two previous frames divided by a time interval between the two previous frames. The method includes predicting a next position of each of the objects based on the first position of each of the objects and the speed of each of the objects, and determining which of the objects remained in the sensing region based on the predicted next positions.
