Implementation of a Picture Digitizer and Display for Image Processing Operations.

Abstract

The purpose of this study was to implement Spatial Data System's EyeCom Picture Digitizer and Display on Digital Equipment Corporation's PDP-11/50 minicomputer using the real-time operating system RSX-11M. The tasks involved included the following: operating the EyeCom on the RT-11 operating system to investigate its image processing capabilities; implementing of Drexel University's software conversion package for the RSX-11M operating system; preparing a EyeCom Operator's Manual for RSX-11M; developing a Pseudocolor option using the RAMTEK GX-100A Color Raster Scan Display. With the completion of these tasks, the EyeCom can now do the following image processing operations: picture digitization, magnification, averaging, gray-scale reduction, contrast enhancement, spatial filtering, shifting, reversal, edge enhancement, picture noise reduction, and histogram distribution. The result of these operations can be displayed on the RAMTEK GX-100A Color Raster Scan Display. (Author)
