A scene matching approach which utilizes histograms of edge directions is presented. This approach is expected to have utility in matching imagery taken by different sensors and matching images taken at different times of the day or night. Examples of using this technique to match white hot to black hot FLIR imagery and match synthetic to FLIR imagery are shown.
