Some Studies in the Interactive Design of Character Recognition Systems

A project to develop an effective tool for the interactive design of optical character recognition systems is described. The initial design system and several techniques and experiments to improve the system are also reported. Results of an experiment to design a recognition system for typewritten characters are included. The recognition logic required 11.3 man-hours to design and recognized over 99.9 percent of its test characters. It is also small and can run at high speeds on standard digital computer systems. The results of several experiments and recommendations for future experiments to extend these results to hand-printed characters are also included. The development of more powerful multilevel logic forms and suggestions for making these forms easy to use in an interactive design environment are particularly important results of these studies.
