For images taken by infrared cameras, the RMA has performed a simple preprocessing, followed by edge detection. Since most of the mines are circular, they will be ellipses on binary, edge detected images; because of occlusion and noise, these ellipses are not, in general case, continuous. Therefore, The RMA develops shape recognition tools that are able to detect partially occluded ellipses [17]. Two examples of obtained results are shown on fig.(25).
