15.5.601 subshiftc

subshiftc, im1, im2, xoff, yoff [, apod]

Determines the sub-pixel shift between two two-dimensional images im1 and im2 and returns the found shift (measured in pixels) in xoff and yoff. If apod is specified, then apodization is applied to the compared images. The merit value (i.e., the measure of goodness) is returned in global variable !meritc. This routine favors algorithm symmetry over execution speed; i.e., the results for a positive shift are nearly equal to the results for the corresponding negative shift.
