Abstract
A method of processing an image includes the steps of computing a plurality of line averages for a first image; identifying a set of pairs of line averages having high edge strengths; identifying a set of maximal pairs of line averages from among the set of line averages having high edge strength; expanding each of the maximal pairs of line averages into line stacks to form a set of line stacks; applying the set of line stacks to a second image so as to compute lines averages for the second image; shifting the line stacks to center the stacks on areas of highest edge strength and computing a distance between line stacks of the first and second images.
