Abstract
Character recognition processing wherein each of a batch of documents is scanned to produce corresponding scan data signals forming a rectilinear data array of binary bits at the intersections of a rectangular coordinate grid. These signals are stored and processed by a recognition algorithm to produce identity signals for recognized characters. Groups of non-recognized characters are presented simultaneously to permit rapid identification by inspection. The identification of recognized characters is verified at high speed by simultaneously presenting the character images as respective groups sorted to have the same recognized identities. High accuracy recognition is assured by including with the stored characters to be verified a number of images of purposely-incorrectly-identified characters, i.e., bogus errors. At the end of predetermined processing segments, such as one batch of documents, the results of verification are examined to determine how many bogus errors were caught by the operator. If not all of the bogus errors present were caught, the operator may review the segment until all are caught. Statistical analysis of the data will provide assurance of high accuracy recognition.
