Display devices in image processing.

Hardware arrangements and methods are proposed in which optoelectronic devices, such as image converters and special purpose CRT's, are used for image processing operations, e.g., correlations-integral transforms, such as the Fourier transform, filtering, implementation of special algorithms, and one-dimensional functional representations. These operations are to be performed in parallel or partly in parallel at an over-all speed far exceeding that of a fast digital computer, with the output appearing as sequential electric signals. The accuracy will be adequate for experimental but not for analytic inputs. Specific recommendations are made on needed improvements in the performance of display devices and the standardization of developmental models, which would permit optimization of the proposed systems and increase their range of applicability.
