Abstract : The report describes a study of the recognition of handprinted symbols for a computer-aided mapping system, which was performed under a contract with USAETL, Fort Belvoir, Virginia. Software is used to recognize a constrained set of handprinted symbols (which have been digitized on a drum scanner), and identify their X-Y coordinates for creating point symbols or descriptive information on map overlay negatives. Pattern classification is accomplished using discrete Fourier transformations. Recognition rates for the character sets averaged out at about 96%. (Author)
