Abstract:

A background suppression algorithm for the infrared image based on the local structure tensor is presented,which combines the local structure tensor and bilateralfiltering.In the algorithm,the standard derivative of the local structure tensor is used as the criterion for whether the bilateralfiltering is executed,and the weighed coefficient with bilateralfiltering is adopted to achieve background estimation.The structured background suppression and the targetsignal enhancement are fulfilled.Experimental results show that the presented algorithm achieves better background suppression than the partial differential equation method and the twodimensional LMS filter.
