A system for graphical image analysis
Abstract
A description is presented of a digital image processing system for handling graphical data. The application of self-scanning linear photodiode arrays as a scanner makes this system different from other image digitizers using conventional tube-type scanners. It simplifies the design aspect of the system, and is a more economical method to handle graphical images. The strip chart scanner is currently being interfaced to an Air Force supplied minicomputer and will be delivered for on-line duty. Stand alone data acquisition and analysis will be provided by special purpose software. The final evaluation will be how the system performs over the next three years. An enormous amount of data is still being generated on strip chart paper and this machine scanning approach is the only practical means of reducing and analyzing that data. This type of image processing technique also has several potential applications in areas such as optical character recognition, facsimile, and graphical signal processing in medicine, geophysics, and electrocommunications.
