Cross Correlations for Two-Dimensional Geosynchronous Satellite Imagery Data,

Abstract

The usage of the FFT and other fast unitary transforms for the determination of cross-correlations of geosynchronous satellite images is investigated. The basic background information on the techniques is summarized and a computer program embodying the two-dimensional FFT approach adopted is presented and its usage discussed. (Author)
