1. A method for estimating a position of moving objects in a set of image data, comprising the steps of: identifying a position of an object in a first frame of image data acquired at a first time; determining that the object is undetected in a second frame of image data acquired at a second time; estimating movement of the object to determine its estimated position in the second frame of image data using at least one of velocity and acceleration of the object and time between frames of image data; and using the estimated position to determine a position of the object in a third frame of image data acquired at a third time.
