Claim One:
1. A method for correcting results of optical character recognition (OCR) comprising: scanning a document image; performing OCR classification on the document image; clustering symbols from the OCR classification based on shapes of the symbols; creating super symbols based on first differences in the shapes of the clustered symbols exceeding a first threshold and that provides a display that emphasizes localized differences in similar symbols; displaying a carpet of super symbols for analysis testing; storing the clustered symbols when the carpet of super symbols passes all of the analysis testing; creating additional sub groups of super symbols based on second differences in the shapes of clustered symbols exceeding a second threshold and returning to displaying step when the carpet of super symbols passes most of the analysis testing; rejecting clustered symbols when the carpet of super symbols fails most of the analysis testing; and storing rejected clustered symbols by manually keying-in the symbols.
