Claim 15:
16. The method of claim 15, wherein the step of correlating each local template window to the larger search window further comprises:
for each possible template offset position relative to the larger search window, extracting pixels from the search window that correspond to the template offset position;
for each pixel in the template window,
computing a relative contrast metric M from pixel values in the template and search windows for the first and second pseudo-pan images, respectively;
raising the relative contrast metric M to a power X where X>1;
weighting the M to emphasize center pixels in the template window and de-emphasize edge pixels in the template window; and
computing a running sum of the metric M as a cost;
assigning the cost to the correlation surface for each template offset position.
