Abstract

This is a character recognition system in which the recognition parameters are a function of character position. The system must be capable of recognizing multiple characters, such as the $ and cent amount on a personal check. In such an instance, the parameters used in the character recognition system are varied as a function of a character relative to other characters. For example, in the case of the amount written on a check, the character recognition system is designed such that the parameter settings cause a character to be reported more frequently for digit n, when counting from right to left, than for digit n+1, but the (n+1) reported character has a higher probability of being correct than the nth reported character.

Character Recognition Using Parameters Which are a Function of Character Position

This is a character recognition system in which the recognition parameters are a function of character position. The system must be capable of recognizing multiple characters, such as the $ and cent amount on a personal check. In such an instance, the parameters used in the character recognition system are varied as a function of a character relative to other characters. For example, in the case of the amount written on a check, the character recognition system is designed such that the parameter settings cause a character to be reported more frequently for digit n, when counting from right to left, than for digit n+1, but the (n+1) reported character has a higher probability of being correct than the nth reported character. Such a character recognition device makes few errors when significant amounts of money are involved, and a larger number of errors when less significant amounts of money are involved. Such a system is also useful in signature verification since most people take greater care when writing the first few characters in their name.

Such a character recognition system is illustrated in the flowchart. Initially, as set forth in block 2, the next character to be analyzed is selected. Then, as indicated in block 4, it is determined how important it is to recognize the selected character. If the character is of little importance, a signal is sent via line 6 to block 8, whi...
