Thompson, K A

This is an initial report of an investigation to determine the practicality of using minicomputers for automated interpretation of stereo pairs. The procedure involves the use of autocorrelation procedures to match features from the stereo pairs, determine the height of the feature, and repeat for the rest of the image. This is a time consuming process, requiring some simplifying algorithms to limit the area of autocorrelation and possibly the method of autocorrelation. Once topography has been determined, a method is needed to analytically determine the surface roughness, one possibility being the determination of the fractal dimension, if the surface is fractal. This fractality can then be used as a characterization index to compare to other materials or to cross correlate with other experimental techniques.
