Automatic Buried Objects Detection in Different Soils Based on Active Contours

An efficient approach to detect and to localize buried objects using a continuous wave metal detector in different soils is presented. The algorithm can minimize the distracting influence from the soil and localize the buried objects with better precision. This approach used an external force called virtual electric field, to guide the deformation process to active contours boundaries which correspond exactly to the buried objects with and a computed multichannel gradient applied to the obtained metal detector images. The quality of the results can be significantly improved by employing this approach. This can be very useful for higher level vision processing.
