Abstract
Various features relate to processing a scanned image to facilitate accurate locator pattern identification and/or detection of the corner locations of the locator pattern. In some embodiments to facilitate the identification of corner points the scanned image is processed to reduce the effect of noise and/or other damage on the subsequent location identification process. Individual white pixels which have black pixels on four sides are converted to black as part of the processing while multiple white pixels adjacent each other are left unaltered. In some embodiments processing does not alter the color of black pixels. Corner points of the locator pattern are identified through additional processing and identification of line segments satisfying an expected black, white, black, white, black segment portion ratio.
