                  Laplacian pyramid image architectures has been
                  traditionally performed in a "coarse" to "fine"
                  fashion. In the present paper, we show that by
                  computing cross-correlation within each level of the
                  pyramid independently, and considering the sum
                  across (expanded) levels, a significant improvement
                  in Peak to Correlation Energy (PCE) (Kumar and
                  Hassebrook, 1992) is obtained. This result is
                  illustrated with a number of numerical examples. },
