Abstract
  • This is a report describing the limitations of optical character recognition using the mask-matching principle. Conclusions are supported by the results of an experimental system built for the purpose of reduction to practice. Formulas are derived describing the limitations of a mask-matching system. Given desired character reading speed, a specified character set, and reliability requirements; system specifications such as disc size, RPM, mask size, light source intensity, and output signal levels can be obtained. Appropriate numbers are inserted representing the experimental system for empirical verification. Then using the limitations of present development an optimum mask-matching system is specified. Finally, areas for further development are outlined.
