ABSTRACT:
A process comprising computing a histogram of pixel intensity data collected from a digital image of an optically readable symbol including light and dark elements, thresholding the histogram to classify individual pixels as light pixels, dark pixels or gray pixels, thresholding only the portion of the histogram corresponding to gray pixels to re-classify the gray pixels into dark pixels, light pixels or unresolved gray pixels, and heuristically analyzing each string of unresolved gray pixels to determine the elements of the optically readable symbol that created the string of unresolved gray pixels. An apparatus and system to implement the process.
