针对背景不动情况下提取红外图像运动目标,提出了一种基于连续四帧序列图像精确检测多运动目标的算法,并用软件仿真了该算法处理图像的效果并与其他方法进行了对比。经试验证明该方法算法简单,实时性好。对单目标、多目标、室内、室外、简单和复杂背景的红外序列都可以得到较好的检测效果。能够有效地去除背景和噪声,精确地确定运动目标位置,有利于后续的目标跟踪,算法适于实时应用。

英文摘要：

It is very important to use infrared sequence imaging for target automatic detection in the modern defense technology. Aimed to infrared sequence image in still background, a new method based on four sequence images is proposed to detect moving target precisely. Experimental images are simulated by software. The result shows that the proposed method is easy and its practicality is good. Real target or targets from indoor or outdoor and simply or complex backgrounds can be detected properly. The noise and background is removed and the position of targets is properly lined. These can all make for the post procession of computer vision and is easier to be applied in a real-time environment.
