Abstract
A method for processing backwards documents in a document processing system involves a reverse recognition algorithm. The document processing system includes a magnetic ink character recognition (MICR) reader. A waveform is determined for a magnetic ink character string on a document. A forward recognition algorithm is applied to compare the determined waveform to a set of known character profiles. In a case where the magnetic ink character string remains unrecognized after application of the forward recognition algorithm, a reverse recognition algorithm is applied to compare the determined waveform to the set of known character profiles. The reverse recognition algorithm considers the determined waveform as resulting from the document being oriented backwards when passing though the magnetic ink character recognition reader when comparing the waveform to the set of known character profiles.
