Abstract
The purpose of this study was to implement Spatial Data System's EyeCom Picture Digitizer and Display on Digital Corporation's PDP-11/50 minicomputer using the real-time operating system RSX-11M. The tasks involved included the following: operating the Eye-Com 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 User's Manual for RSX-11M; developing a Pseuocolor option using the RAMTEX 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 RAMTEX GX-100A Color Raster Scan Display.
