摘　　要：在分析红外弱小目标检测的检测概率和虚警率的基础上,引入了一种基于窗口结构的红外弱小目标检测方法.该方法无需进行图像差分,利用局部小范围内目标相对背景的灰度变化检测目标,可以在较低信噪比的情况下获得较高的检测概率和较低的虚警率.实验表明了该方法的有效性.On the base of analyzing the detecting probability and the false alarm rate of infrared dim and small objects detection, a new method based on window to detect infrared dim and small objects was introduced. The method which uses the relative gray change of objects and background in local small range can get a higher detecting probability and a lower false alarm rate. Some experiences proved that a good result to segment and get dim and small objects can be achived without image difference.
