The location and orientation of a barcode block is determined by first producing an image of the document that excludes the barcode block and producing a second image wherein the spaces in the barcode block have been deleted thereby providing a solid rectangular block. The two images are subtracted to reject large background clutter while displaying with certainty the full image of the barcode block. Thereafter, down-sampling occurs to remove small clutter and other non-barcode objects while locating the centroid of each barcode block. The image containing the centroid is up-scaled and used to calculate the position of the barcode block in the original document for use by a barcode reader.
