IR target detection under open country scene with a complex background

IR target detection is a key problem in monitoring for open country scene with a complex background. The quantity and the target\|similarity of the background objects make the detection even harder. A practical IR target detection algorithm is presented here. It includes two processing steps. First, to match the scene, extract the movement information, and then perform the coarse detection based on it. Second, to perform the fine detection based on the time\|space relativity of the movement. The low missing rate of the coarse detection and the low false rate of the fine detection guarantee the stability of the algorithm. Both the target and its region location are determined by using the algorithm. The experiment results are shown in the paper. \;
