  • Patent number: 4277775
    Abstract: A character recognition system is disclosed in which feature characteristics of an analog waveform representing an unknown character are applied to a plurality of templates each representing a known character and consisting of a number of windows in which the feature characteristics of the known character are to be located. Hardware implemented circuits compare each feature characteristic of the unknown character with each window of the template. If a feature characteristic is found outside the window, the distance between the location of the feature characteristic from the location of the window is found. The sum of the distances for each template is generated and the templates having the two minimum distances are selected and evaluated to determine if a character can be recognized from the value of the two minimum distances.
