Abstract :
Comparative study of different background subtraction methods has been performed. A criterion for quantitative comparison of different algorithms has been introduced. Based on this criterion, performance of different algorithms has been tested for scenarios with relatively smooth ground surface and very rough one. Optimal algorithms for each type of surfaces have been determined. Different ground bounce removal techniques influence GPR imaging. This dependency has been evaluated, after focusing, by means of the ratio between signal energy and remaining clutter. A very exigent scenario has served to this end.
