The Adaptive Filtering method enhances the determination of linear structures in satellite images, by noting the direction of the maximum gradient, that exceeds a preselected threshold. The structure-tracking method considers the information from the maximum gradient, in order to determine quantitative parameters, such as length, efficiency, mean direction, histogram of the directions, along each linear feature. This study links Adaptive Filtering to the processing of radar images, develops a program using the Structure-tracking in conjunction with information about the gradient, and provides quantitative information to be used for tectonic interpretation.
