ABSTRACT:
A method for tracking an aimpoint with arbitrary subimages as described. The method comprises the steps of acquiring an aimpoint (50) on a target and a set of subimages (80) arbitrarily associated with the aimpoint by a sensor in a field of view. For a first time, the dimensionality of each subimage (82) and a normalized distance (54) from each subimage to the aimpoint are determined. For a second time, at least one of the subimages is reacquired (56) and the subsequent location of the aimpoint is estimated (58) based on the subsequent location of the subimages, on the normalized distances, and, where a subimage is one-dimensional, on a maximum eigenvector associated with the subimage.
