Paper Abstract

At present, most measurements on aerial photography are made with image-comparing instruments and shearing or filar measuring microscopes. And in most automated systems, stereo images are first digitized and then correlated with the aid of a digital computer. In all likelihood, some of these techniques can be simplified or improved by Optical Power Spectrum (OPS) techniques.
