卫星红外图像点目标检测预处理

A new pre-processing algorithm for dim target detection in satellite IR image frame

对卫星红外图像点目标检测预处理方法做了研究,采用线性滤波器和非线性滤波器并行对图像进行预处理,仿真实验表明该方法可以在保证很高的检测率的同时大大降低虚警率,为后续处理提供有力支持。算法简单可行,利于硬件实现。

In this paper,pre-processing algorithms for dim target detection in satellite IR images are discussed.A new algorithm is proposed to pre-process images by parallel linear-filter and non-linear-filter.The experiments show that the new algorithm in the paper can get high detection rate and low false alarm rate.The new algorithm is easy and effective to real-time operating.
