Paper Abstract

A system to perform digital analysis of graphical images has been developed and utilized in the analysis of six channel strip chart recordings over the past three years. Silicon linear photo-diode arrays were employed as the image digitizer, simplifying preprocessing techniques in the scanner. The scanner consists of control and logic electronics, light source, lenses, paper transport mechanism and six 128 x 1 photo-diode integrated circuit arrays. The graphics scanner is interfaced to a minicomputer system which includes display, storage, and analysis capabilities. The scanner's preprocessing includes threshold detection of edges and removal of reference grid lines from the digitized image. This system has been used to perform statistical analysis on wideband communications data as recorded on six channel strip chart recordings by the United States Air Force Communications Service at Richards-Gebaur Air Force Base. Several thousand meters of strip chart have been analyzed over the past three years, successfully demonstrating the utilization of solid state scanners and computerized analysis of graphical data.
