Abstract: Improved operation of character recognition systems for reading magnetized ink characters is obtained by utilizing a Kalman-type prediction filter following the output of the amplifiers used for amplifying the signals obtained by scanning the characters with a magnetic read head.

Abstract: 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 (20) is compressed (26) by data compression techniques and the compressed data is sent over a high speed data channel (30) to a high speed mass storage device (40) which receives and temporarily stores the data. A lower speed mass data storage device (54), 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 (24) 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.

Abstract: A character recognition system including a timing subsystem, comprising a base oscillator or clock (13) and adaptive timing circuits (39) driven by the base clock to provide a plurality of timing pulses for timing the operation of the entire system. The timing circuits are governed in part by delay circuits which are in turn controlled by the amplitude and location of peak signals derived from scanning earlier pulses.

Abstract: An improved character recognition system for bar coded characters particularly of the form designated as "CMC7," comprising characters formed with seven vertical bars known as strokes, which are separated by intervals of varying widths, the narrow and wide spacings in the intervals or spaces between the strokes comprising the code for the character. The electrical waveform obtained by scanning the characters with a suitable scanning head is differentiated and the signal and the derivative thereof are used in circuits which measure the inter-stroke intervals. Use of the derivative signal from the scanning or read head enhances reading by using it to locate the edges of the printed strokes.
