Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 19:
20. The method of claim 15, further comprising:
in step b), extracting a second pair of correlation offsets X and Y including fractional portions from the correlation surface,
in step d), resampling the pixel values within the local template window of the first pseudo-pan image or the larger search window of the second pseudo-pan image using fractional portions of the second pair of correlation offsets X and Y;
in step e), using the resampled pixel values for the second pair to correlate the local template window in the first pseudo-pan image to the search window in the second pseudo-pan image to produce a second resampled correlation surface;
extracting first and second final pairs of correlation offsets X and Y from the respective resampled correlation surfaces;
computing a FOM for a peak in the second resampled correlation surface; and
accepting one of the final and second final pair of correlation offsets X,Y based on their respective FOMs.
