Development of an on-Line Image Processing System for the Linc

摘要

The development of an on-line image processing system for the LINC computer is described with both hardware and software details being considered. The purpose of the system is to operate on various types of optical images endeavoring to process them so that a maximum amount of useful information is retrieved for final interpretation by the observer. Besides other processing techniques, contrast enhancement and subtraction have been implemented into the system to achieve this purpose. A mathematical model of the system is investigated and equations describing its capabilities are derived. Results showing several pictures before and after processing as well as data verifying the mathematical model are also presented. (Author)
