Abstract
A method of detecting land mines includes pre-processing a raw laser interferometer image, processing pre-processed image by calculating one or more derivatives having one or more peaks, along vectors extending in at least two different directions, mapping the peaks of said derivatives to create a derivative map, and detecting an anomalous signature in the derivative map.
