基于目标模型的红外弱小目标预检测

Pre-detecting Weak and Small Infrared Target Based on Target Model

为解决高空背景中低信噪比运动点目标的检测问题,本文提出了一种利用红外弱小目标和背景的不同模型来实现检测小目标的预检测方法。根据在同一帧图像中红外弱小目标与噪声点在局部图像中特性的不同,提出检测局部图像中一个点与目标模型的相似程度来判断是否为红外弱小目标的预检测方法。实验表明,该方法可以有效提高单帧目标的信噪比,可用于噪声环境的红外弱小目标检测。

The characteristics of weak and small target are different from these of clutter in smaller area, which is used as a pre - detection weak and small IR target. Experiments are presented to demonstrate that this method can enhance the SNR and can be used in clutter background.
