Abstract :
An adaptive Butterworth highpass filter is presented to detect a small target under a sea-sky complex background. By calculating the weighted information entropy of different infrared images, the cutoff frequency of the filter can be changed adaptively. Experimental results show that it is a robust small target detection method.
