An experimental laboratory for pattern recognition and signal processing

Abstract: An interactive computer-controlled scanning and display system has been in operation at the IBM Thomas J. Watson Research Center for three years. The system includes two flying-spot scanners and a TV camera specially interfaced to a process control digital computer, dot-mode and vector displays, analog input and output facilities, and a variety of other experimental equipment. The system design and programming support are described and typical applications in scanner control, optical character recognition, and image processing are presented.

System study of a dial-up text reading service for the blind

Abstract: This paper describes a recent feasibility study of a system concept that could allow blind persons access on demand to the printed page. A portable, user-controlled scanner, based on the Optacon direct-translation reading aid, would collect image information from any printed text for presentation to a computer and optical character recognition unit, remotely connected via dial-up telephone lines. The OCR unit would recognize the letters of the text, the computer would assemble them into words and phrases, and intelligible speech would be returned to the user. The study indicated that such a system was feasible, or close to feasible, within the state of the art in the pertinent areas of development and that its cost might not be exorbitant in comparison with existing services for the blind.

A syntax-directed approach to pattern recognition and description

Abstract: Pattern recognition has held the attention of researchers for quite some time. Early efforts were in optical character recognition and were intended to provide easier and more rapid communication from man to machine. In more recent years, this research has expanded to include the processing of pictorial information, such as that from high energy physics or medical research.

Coordinate transmission for character recognition systems

Abstract: An optical character recognition system in which position data is detected by other than addressing a document field and is tagged on to a character identifying data byte. For documents in which the position of the character conveys information and for which the selected field to be scanned does not satisfactorily identify the character position, the scanning beam is tracked and converted into a position data byte when a character is detected. The position data byte is sent along with the character data byte to a utilization means.
