A Character-Recognition Study

A study of the single-gap-scan approach to character recognition, using an IBM 650 for simulation, is reported. Ten specially designed digits were used in this study. Character recognition is discussed in terms of some simple concepts from n-dimensional geometry. The main contribution is an effective method for using a computer to aid in the design of the type font. This procedure is a natural development of the vector approach. Experimental results show the sensitivity of the system to phasing. An expression is given for a “quality factor.” The relationship of this factor to errors and to ink density is illustrated.
