ABSTRACT:
Banking apparatus for reading numeric information on bank checks, drafts and like documents. An electronic black/white pixel image of the numeric information is analyzed by a system capable of reading unconstrained, constrained, printed and typed numeric characters, locating the division between dollar and cents amounts. The invention also reads overlapping touching and not touching characters. A check is fed (330) to a scanner (331) and converted to a black and white image. A courtesy amount field (CAF) on the check is located by a CAF locator (332) and is provided to a recognition system (333).
