%X An algorithm for moving point target detection from complex background based on Tophat transform is presented in this paper.At first,low frequency background suppression is adopted to single frame image by morphologic Tophat filter.In order to strengthen the target points,the difference of multiple frames of filtered images is accumulated in sequences.In the final frame,bi-directional chain is a adopted to detect the target point's track according to the chain's length.Experiment results show that the method in this paper is promising.
