A Digital Image Processor For Automatic Target Cueing, Navigation, And Change Detection
Glenn E. Tisdale · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1977
This paper describes the design and application of a digital processor for the automatic recognition of targets in reconnaissance images and for the precise registration of two images of the same terrain area. The problems of information extraction and bandwidth reduction in raw sensor data are considered and how they lead to the evolution of a common preprocessing approach. Three applications of the preprocessed data are then examined; (1) automatic cueing of targets in sensor displays, (2) automatic registration between images to update navigation systems or to correct image geometry, and (3) detection of the changes between image sequences. The paper concludes with a discussion of the combined use of recognition and registration functions in targeting problems.
