Abstract:

Machine recognition of handprinted characters is accomplished on a reference alphabet consisting of the 47 characters of the FORTRAN Programming Language alphanumeric -., and blank. The system is comprised of an optical scanner reader OSR which digitizes data with a maximum vertical resolution of 48 lines, and a software measurement-decision system. The OSR operates at 10 characterssecond in conjunction with an XDS 930 computer, and produces digitized characters on magnetic tape. Recognition is done at rates of 3.5 to 6 characterssecond off-line via the measurement-decision system operating on a CDC 64006600 computer system. The measurement system generates a directed graph representation of each character and extracts a primary feature vector. This vector consists of cavity both open and closed and spur information. Other specialized measurements are made later in the recognition process under the control of a deterministic decision tree. Author
