System and method for enhanced character recognition accuracy by adaptive probability weighting

摘要

A data processing system and method are disclosed for selecting which one of several character recognition programs should be used to optimize the accuracy in recognizing characters in a field in an image of a document form. Consideration is taken of the character form and field type for particular characters and an optimized selection is performed on a realtime basis among the several candidate character recognition programs which could be applied. The resulting character recognition operation has its accuracy maximized for reading a wide variety of character forms and field types in recognition of preprinted forms.
