GRAPHICAL-DATA-PROCESSING RESEARCH STUDY AND EXPERIMENTAL INVESTIGATION.

Abstract

A method for making a mask-plate for the 1024-image preprocessor is described in detail. The masks are organized in pairs and with the appropriate circuitry function as edge-detectors. Recognition experiments on hand-drawn map symbols parallel to those previously reported for the 100-image preprocessor have been carried out using the 1024-image preprocessor. In order to extend the work on mask design by simulation, it is desired to input a low-resolution TV picture into the SDS 910 computer. The standards chosen are 24-line and 120-line. Seven methods for interfacing the TV camera output with the SDS 910 have been examined. The shift-register method has been selected for implementation. (Author)
