海天背景红外图像小目标自动定位方法

通过对舰载红外警戒系统成像进行分析,提出了一种基于交叉算法的海天背景红外小目标的自动定位方法.其基本思路是根据红外图像的特点,首先通过Radon变换域极大值点提取海天线,然后沿海天线平行的方向取与海天线平行的直线,进行频率突变点的检测,最后由海天平行线和频率突变点处坐标共同对红外图像小目标进行定位.试验结果表明,该算法能快速、准确地对目标自动定位.

A Small Target Auto-orientation Method of Infrared Image with Sea-sky Background

An auto-detection method based on 'cross algorithm' is introduced for infrared image small target(detection.) By utilizing the method on ship infrared search and track system,the algorithm proves to be ability to(detect) the small infrared target rapidly and exactly and with high detection ability.The method includes the following steps.First,an auto detection of sea-sky-line is implemented through Radon transform.Then nearer lines paralleling to sea-sky-line is availed to detect the break point of frequenc...
