Patent Images

1. In a process for verifying the tentatively determined identity of recognition-processed characters, the steps of:

  • storing data representing the images of a number of characters which have been tentatively identified in a predetermined computer-controlled algorithm providing a recognition-processing segment;

    storing data representing the images of a number of characters which are purposely-incorrectly-identified (PII);

    sorting said stored tentatively-identified and PII image data into groups of characters of the same identification;

    merging by combining the tentatively-identified characters of one group with a number of said PII characters from a corresponding group having the same (but incorrect) identification as said one group;

    simultaneously displaying in a single uniform composite array a number of stored character images from each of said groups of the same identification;

    determining by inspection the presence of characters in the displayed groups failing to have the characterization common to those groups of the same identification;

    determining those characters failing to have said common characterization which were purposely-incorrectly-identified (PII);

    developing statistics reflecting the number of PII characters found in said inspection;

    determining from said PII statistics whether a desired sufficient number of incorrectly-tentatively-identified characters has been found; and

    when an insufficient number of such characters has been found, inspecting said displayed groups again in an effort to find additional characters failing to have the characterization common to those groups.
