A method for enhancing a check code line image of a captured document such as a bank check. The method includes capturing an electronic image of a document; locating a code line region within the electronic image of the document; and performing a localized video gain on the code line region.

Enhanced check code line image capture for improved OCR

A system, method and program product for rotating a first image in an image buffer such that the resulting, rotated image is substantially free of an aliasing error, i.e., broken lines, stair stepped edges, etc., is disclosed. An algorithm is applied to the first image that uses weighted sums of data points of the first image to create the rotated image. The weighting is based on the skew angle and data point location of the first image. The resulting rotated image also has a reduced data storage space requirement compared to rotated images created by prior art techniques.

Image rotation with substantially no aliasing error

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.

A system 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.

A peripheral interface device that is adaptable into a computer system and which provides a communication interface for a plurality of external devices. The peripheral interface device comprises: a plurality of transfer control logic (TCL) modules, wherein each TCL module provides a dedicated interface for an associated one of the external devices, and wherein multiple TCL modules can communicate in parallel with their associated external devices; and a dual port memory (DPM) device that is in communication with an input/output bus of the computer system, wherein the DPM device can selectively communicate with each of the plurality of TCL modules.

Peripheral interface system having dedicated communication channels

A document processing system directs documents at a high rate of speed past an optical scanner which captures written information on the documents as video image data. The video image data is directed over a data channel to a host computer system where the data is stored on a mass data storage device for subsequent retrieval. A buffer is provided between the scanner and the data channel, which receives data a rate which varies in relation to the amount of information present on the documents. Data is extracted from the buffer at a rate which is limited by the host computer's channel transfer rate. A control means is associated with the buffer and is operable for controlling a hierarchy of actions ranging from slowing down the incoming data stream to stopping the data stream altogether in order to prevent any loss of video image data due to overfilling of the buffer.

System for scanning documents without loss of image data

Documents, such as bank checks, are processed at a high rate of speed on an image processing system which optically scans the documents and converts optically perceptible data on the documents into video image data. The video image data from the scanner is compressed by data compression techniques and the compressed data is sent over a high speed data channel to a high speed mass storage device which receives and temporarily stores the data. A lower speed mass data storage device, such as an optical disk, is connected for receiving at a lower data transfer rate the compressed video image data and for storing the video image data for subsequent retrieval. The system also includes real-time quality control systems for monitoring the quality of the image data to detect the existence of unacceptable image quality data and for generating a signal which can be used for immediately stopping the generation of unacceptable quality image data.

Document image processing system

A method and apparatus are disclosed for reading a two-dimensional bar code having bars located nominally at predetermined pitch increments. The invention provides a method and apparatus for reading a two-dimensional bar code and dynamically segmenting it into individual bars on a real time basis, as it is read. The segmentation is done on a bar-to-bar basis, and may be adjusted for an individual bar as necessary. The method and apparatus locate the bar data, scan it, and create a profile vector having elements based upon the amount of image data in each scan. The vector is compared to a predetermined stored set of vector elements representing the likelihood that each scan line of image data contains bar image data. Those scan lines of image data corresponding to a bar image are sent to recognition logic and those scan lines of image data corresponding to a space are disregarded.
