Abstract
A method and apparatus for evaluating a confidence level of a decoded barcode value is disclosed. A digit score is assigned to a digit within a barcode. When decoding the barcode, if a deduction is required to decode the digit, then the digit score for the digit is reduced accordingly. After all the digits within the barcode have been decoded, a total score of a decoded barcode value can be determined by adding all the digit scores for all the digits within the barcode. The total score of the decoded barcode value is reduced if a checksum is used to ascertain the value of any digit within the barcode. The decoded barcode value can be accepted only if the total score exceeds a predetermined value.
Claims15
A method for determining a confidence level of a decoded barcode, said method comprising:
- assigning a digit score to a digit within a barcode;
- reducing said digit score if a deduction is required to decode said digit;
- determining a total score of a decoded barcode value by adding digit scores for all digits within said barcode;
- reducing said total score if a checksum is used to ascertain the value of any digit within said decoded barcode value;
- and
- accepting said decoded barcode value if said total score exceeds a predetermined value.
A computer program product residing on a computer usable medium for determining a confidence level of a decoded barcode value, said computer program product comprising:
- program code means for assigning a digit score to a digit within a barcode;
- program code means for reducing said digit score if a deduction is required to decode said digit;
- program code means for determining a total score of a decoded barcode value by adding digit scores for all digits within said barcode;
- program code means for reducing said total score if a checksum is used to ascertain the value of any digit within said decoded barcode value;
- and
- program code means for accepting said decode barcode value if said total score exceeds a predetermined value.
A mail piece barcode evaluation system capable of determining a confidence level of a decoded barcode, said mail system comprising:
- means for assigning a digit score to a digit within a barcode;
- means for reducing said digit score if a deduction is required to decode said digit;
- means for determining a total score of a decoded barcode by adding digit scores for all digits within said barcode;
- means for reducing said total score if a checksum is used to ascertain the value of any digit within said decoded barcode value;
- and
- means for accepting said decoded barcode value if said total score exceeds a predetermined value.
