摘要
提出了图像局部能量比的概念,并针对空中目标图像特点,给出了一种基于局部能量比的红外弱小目标检测方法。该方法基于单帧图像即可实现红外点目标检测,算法简单,耗时较短,可以实时检测;图像局部能量比对图像噪声不敏感,故该检测方法对图像信噪比要求较低,具有强抗干扰性,便于工程实现。文中给出了检测算法的具体实现过程,并用真实空中红外弱小目标图像进行了检测试验。试验结果表明该方法对空中红外弱小单目标和多目标均具有令人满意的检测效果。
The concept of local energy radio is proposed, and the local energy ratio change of infrared image is used as detection criterion to locate the sky background infrared small targets. A useful algorithm is designed, which is simple, fast, insensitive to noise, and the detection process is presented in this paper. The detection experiments are performed for a set of real infrared images of small target on sky. The experimental results prove that the proposed approach is effective for detection of infrared image of small targets.
