Abstract
A system and method for correcting defects in a black white image. A character recognition system is disclosed that processes character data from a black white image, including: an edge smoothing filter that examines blocks of pixels in the black white image to determine if an indent or protrusion defect exists, and if so corrects the defect in a filtered image; and a recognition engine examines the filtered image and extracts character information.
