Abstract
Where the recognition of small characters (e.g., text, numbers or symbols) expressed in substantially large images is desired, the recognition process may be facilitated by identifying a signature or a pattern of marked identifiers (e.g., bar codes) within the image, and determining where such characters are typically located in relation to the signature or pattern of identifiers. Because the recognition of characters within images typically occupies a substantial amount of a computer's processing capacity, focusing a recognition technique on portions where such characters are frequently located within an image that includes the signature or pattern, and not on the entire image, the time required in order to process an image in order to recognize such characters may be markedly reduced.
