                         approach is based on image moments and the bsp-tree data 
                         structure. We use invariant properties of these moments to 
                         construct a bsp-tree and determine a set of ellipses that 
                         aproximates the object's shape in each frame. These ellipsoidal 
                         structures are matched, which allow to track the object. Motion is 
                         represented by the geometric transformations between the sets of 
                         ellipses and stored in the hierarchical structure. Motion 
                         reconstruction is done by interpolating these transformations.",
