Abstract: A gray scale image cleaning algorithm for improved check code line OCR. An image processing system for processing a gray scale image is provided that includes: a system for generating a first thresholded black white image from the gray scale image; a system for generating a second thresholded black white image from the gray scale image, wherein the second thresholded black white image is generated with a higher threshold value than the first thresholded black white image; and a system for logically combining the first and second thresholded black white images to generate a composite image.

Abstract: A system and method for determining the image resolution of a check image using MICR characters. The disclosed system includes an extracting system for extracting a magnetic ink code recognition (MICR) code line from the document image, wherein the extracting system provides coordinate values for each of a plurality of MICR characters in the MICR code line; a calculating system for calculating a set of resolution values based on the coordinate values of the MICR characters; and a statistical analysis system that calculates a representative resolution value from the set of resolution values.

Abstract: A system and method of detecting and authenticating a watermark on a document such as a check which is supposed to include a watermark having known characteristics to verify the authenticity of the document. A digitized image of the document is stored and processed through tranformation which generates a frequency distribution. That frequency distribution is processed to determine one or more harmonic compared to a stored value associated with the document to determine that a watermark exists and it is the correct watermark.

Abstract: A system and method for adaptive and predictive analysis of sensor readings to track documents in a document processing system. The system comprises: a plurality of sensors for sensing a document, wherein each sensor includes an associated filtering system for filtering sensor readings, and a performance tracking system for collecting performance data; and a control system that and adjusts filtering characteristics of the filtering system based on the collected performance data. In addition, a correlation system is provided for using data from at least one upstream sensor to interpret an ambiguous downstream sensor signal.

Abstract: A system and method for providing positional synchronization of characters in a multi-voting character recognition system. The system comprises a character recognition system, comprising: at least one transducer system for scanning printed character data and generating a plurality of sets of transduced character information; a position collection system for collecting positional data for characters in the plurality of sets of transduced character information; a character position synchronization system for positionally synchronizing corresponding characters from different sets of transduced character information; and a voting engine for receiving the plurality of sets of transduced character information.
