f Radon transform application to 2D processing of potential field data

We have been trying to make use of the Radon transform, a tool for plane-wave decomposition in reflection seismology, in evaluating anomaly trend information from parallel airborne geophysical profile maps, in order to improve the quality of line-to-line interpolation. During our research exercise, we find that this transform has a great application potential in 2D potential field data processing and image processing. In this paper we show how the Radon transform can be generalized and used as a new approach for directional filtering on a gridded data set.
