Method and system for processing backwards documents in a document reader/imager
View Patent ↗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.
1. A method for processing a document having a near side and a far side comprising the steps of:
imaging the near side of the document with a front imaging camera for creating a near side image of the document;
imaging the far side of the document with a rear imaging camera for creating a far side image of the document;
locating a read head proximate the near side of the document;
utilizing the read head for sensing, through the document from the near side to the far side, magnetic ink disposed upon the far side of the document for producing a magnetic ink character data string waveform;
analyzing the magnetic ink character data string waveform by applying magnetic ink character recognition logic including a reverse magnetic ink character recognition algorithm, wherein the reverse magnetic ink character recognition algorithm includes the steps of
determining that the magnetic ink character data string waveform is reversed,
determining that the magnetic ink character data string waveform is inverted, and
determining that the magnetic ink character data string waveform includes a reduced amplitude for
analytically recognizing that the document is arranged in a backward orientation relative the read head for
permitting continued processing of the backward and inverted document; and
swapping the far and near side images with one another in order to compensate for the analytically recognized backward orientation of the document as a result of the determination that the magnetic ink character data string waveform is: reversed, inverted and includes a reduced amplitude.
2. The method of claim 1 wherein the reverse magnetic ink character recognition algorithm further includes the step of
determining that the magnetic ink character data string waveform includes a reduced signal quality.
