Abstract
A method for aligning a pair of digital images includes providing a pair of digital images, wherein each said image comprises a plurality of intensities corresponding to a domain of points in a D-dimensional space, and the pair of images present adjacent views of a same object of interest. A weighting function is applied to each image of the pair of images, wherein the weighting function is centered on the object of interest, the weighting function has a maximum value on the object of interest, and the value of the weighting function decreases with increasing distance from the object of interest. The pair of images is aligned by correlated the weighted intensities on one image with those in the other image.
