An Experimental Laboratory for Pattern Recognition and Signal Processing 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. CACM April, 1972 Herbst, N. M.
