Abstract
A document processing system for processing documents having data printed thereon including markings visible to the eye, but which are not to be read by the system and characters which are to be read by the system includes structure for scanning a document for capturing the color image of the document being processed and for generating a plurality of colored picture elements. Circuity is provided for identifying colors included within the core area and edge of the markings. The colors of the picture elements of the core area and edge of the markings are converted to the color of the background of the document thereby generating a filtered image of the document. An optical character recognition unit is provided for receiving the filtered image of the document representing character information only and for identifying the characters appearing on the document from the filtered image, such that the markings and the background surrounding a character are not distinguishable by the optical character recognition unit.
