Template matching1 via cross-correlation on 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.
