The feasibility of creating a software system to perform automatic rapid updating of AIR target knowledge databases is investigated. Methods of comparing infrared images with CAD model renderings, including object detection, feature extraction, object alignment, match quality evaluation, and CAD model updating are researched and analyzed. A GUI-based software application created to demonstrate object detection, feature extraction, and automatic image alignment is described. An improved method of edge detection based on directional masks and second derivatives of pixel intensities is given. A conceptual software system for rapid updating of AIR knowledge databases is described. A technique for the comparison of images based on line features is discussed. Based on this research it is found that the development of an automatic rapid updating system is feasible.
