The IBM 1975 optical page reader: part III: recognition logic development

The design approaches which were used to specify feature measurement logic, recognition reference standards, and decision functions for a multifont character recognition system are discussed. The importance of an intuitive approach to design, as opposed to a fully automated approach, is emphasized. The nature of the problem required an intimate Interaction between the designers, who investigated complex pattern recognition problems and proposed design alternatives, and the computer, which relieved the designer of routine testing and evaluation of the tentative design.
