1. A method of processing documents to record handwritten numerical entries, a document to be processed including a plurality of first predetermined fields containing handwritten numerical entries and a second predetermined field containing a numerical entry representing the combined value of the numerical entries of said first predetermined fields, said method comprising the steps of:

  • locating said predetermined fields;

    segmenting said predetermined fields into segments, each containing an individual character of the numerical entry of the associated predetermined field;

    subjecting each said character segment to character recognition analysis so as to associate a character therewith;

    assigning a character confidence level to each said character representing the accuracy with which the associated character was recognized.deriving an overall confidence level for each numerical field from the associated character confidence levels;

    automatically computing the combined value of the recognized numerical entries for said first predetermined fields;

    automatically recognizing the numerical entry value of said second predetermined field;

    comparing said computed combined value with the recognized numerical value of said second predetermined field to verify whether said computed combined value and said recognized value match;

    if said computed and recognized values fail to match, displaying the images of the numerical entries in the order of increasing overall confidence levels, whereby a key operator may enter numerical entries from the images;

    repeating said comparing step after each numerical entry from the images; and

    terminating said displaying step when a match is found.
