ABSTRACT:
The present invention employs a method of choosing between the output of two different character recognition systems to improve the rate at which characters are recognized, without significantly increasing the number of undetected substitution errors. If the first recognition system cannot recognize a character, a random probability generator is used to determine whether to use the output of the second recognition system, or alternatively to generate a reject character.
