                         objects in video sequences. Our approach is based on image moments 
                         and the bsptree data structure. We use invariant properties of 
                         these moments to construct a bsptree and determine an ellipsis 
                         that approximates the object's shape. Then, we employ this 
                         information to track objects frame by frame through the image 
                         sequence. The method works well for segmented images with a single 
                         object and we assume that the motion will not change abruptly.",
