Abstract:
1. A method of evaluating a set of printed MICR characters, comprising: providing a template data file representing values of standard template MICR characters; scanning the printed set of MICR characters and accumulating character data representing the scanned characters; first evaluating the character data against the template data file using a coarse analysis method to identify the scanned characters and to identify scanned character characteristics; second evaluating the character data and the scanned character characteristics identified in the first evaluating step against the template data file using a strict analysis method; identifying characters in response to the second evaluating step; wherein the first and second evaluating steps comprise matrix multiplication of the template character data and the accumulated character data and the strict analysis method of the second evaluating step further comprises subtracting from the matrix multiplication a value representing differences between the template character data and the accumulated character data.
