Abstract

See full text

A method and system for performing document image correction using a document reader is disclosed. The method includes generating a document image representative of a document having a deformation; decoding an optical pattern embedded in the document from the document image to determine an optical signature for the document; receiving document classification data associated with the optical signature; and applying an image correction technique to the document image based on the document classification data to generate a corrected document image. A document capable of being read by a document reader is also disclosed. The document includes a substrate and an optical pattern embedded on the substrate. The optical pattern is part of a background pattern printed on the substrate. The optical pattern defines an optical signature unique to the particular class of document and is associated with document classification data for the document.
