Paper Abstract

Applications of high-speed optical power spectrum analysis (OPSA) utilizing telecentric scanning systems for the automated analysis of aerial photography for several relatively simple problems are described. Cloud screening is discussed as an example where a statistical pattern recognition approach is successfully applied to OPS data. Examples of image analysis based on characterization of image structure and orientational content are presented. Projective sampling concepts, which permit image sampling based on ground coordinates in conjunction with a digital data base, are introduced. Finally, use of projective sampling with OPSA is illustrated by an image-to-image cartographic change detection experiment.
