红外图像起伏背景对消的空间滤波方法研究

Research on Space Filtering Methods and Properties for Infrared Image Background Drop

分析研究红外图像起伏背景的起因;针对起伏背景的分布特性,以消除该背景噪声的干扰为目的,介绍了常用的4种不同空间滤波方法的优劣性;通过建立合适的仿真数学模型,用仿真实验方法对所提出的方法作了详细的性能比较,并对得到的数据结果进行了分析和讨论.实验结果表明:对于含有目标信息的起伏背景图像,背景对消的最佳滤波方法,应采用开余滤波法.

The paper analyses the infrared cloudy-background images and their properties. In order to drop this type of background noise, the paper introduces four kinds of space filtering methods for reducing noise, by means of setting up suitable computed math model, experiments has been carried out and many groups of data are presented by selecting different methods and different parameter. Then, the experiment results show that in all of four filtering methods, the open residue filtering method is the best for background drop.
