Abstract
A method for linking front and rear images in a document processing system involves linking the front and rear images by a magnetic ink character code line. The document processing system includes an imaging device and a magnetic ink character recognition (MICR) reader. The method comprises capturing a first image and first MICR waveform for the front side of the document, and capturing a second image and second MICR waveform for the rear side of the document. A forward recognition algorithm is applied to the first waveform to produce a first code line. A reverse recognition algorithm is applied to the second waveform to produce a second code line. The reverse recognition algorithm considers the second waveform as resulting from the document being read from the rear side of the document when processing the second waveform.
