Abstract: This paper introduces a new practical method for detecting moving targets under complex background.The strategy of target enhancement and noise reduction is proposed;the characters and the threshold selection of difference image are analyzed;the method to exclude targets periodically moving and locate the really target is given.Especially,this paper pays more attention on analysis and solutions of image noise,disturbance from scene,and properties of different type images.The method proposed in this paper has been successfully applied in an autonomous control system.
