Abstract
A system for extracting handwritten or typed information from forms that have been printed in colors other than the color of the handwritten or typed information. The information extraction system includes a detector for detecting color values for scanned pixel locations on a printed form; a comparator for comparing the color values with reference color values; an identifier for identifying ones of the scanned pixel locations that have color values that correspond to the reference color values; and an optical character recognition engine for receiving data regarding the identified locations.
