ABSTRACT:
Method for warping first and second overlapping images includes selecting a first set of points in a first image, the first set of points being located in an overlap region between first and second images; selecting a set of tie points in the second image, including individual tie points each of which correlates to a point in the first set of points; selecting from the first image a patch including at least one point from the first set of points and at least one neighboring point; performing shadow detection to determine a percentage of the patch exceeding a predetermined percentage, thereby indicating a shadow; if so, eliminating the at least one point so that it is not correlated with any of the individual tie points, thereby avoiding correlating the shadow in the first image to a shadow in the second image.
