| 摘 要： | 高阶累积量由于可以抵抗高斯噪声的影响而被广泛地应用于信号处理的各个领域。针对复杂云背景下单帧红外图像弱小目标检测的问题,与传统的时空管道滤波方法不同,通过建立合理的数据模型,在抑制缓变背景和噪声的同时,结合小目标局部范围内突变的特点,三阶累积量的计算使得目标在单帧全局检测可检的信噪比达到了1.66。

| Abstract: | A new method to detect the dim small targets in single IR image based on higher-order cumulant is presented.Through the establishment of data model,the method based on the third order cumulant makes best use of the features that the small targets break out in a defined part,which improves the efficiency of detection while decreasing the influence of cloud clutter background in single frame. |
