A system, method, and corresponding computer data product, generates a high resolution reference image, generates a set of rotated reference images from the high resolution reference image, cross-correlates the set of rotated reference images with the high resolution reference image to generate a set of cross-correlation values, and determines that the high resolution reference image is suitable for use in a normalized gray scale pattern find process when the difference between any two correlation values generated by the image cross correlation module is greater than a predetermined threshold value.
