典型的红外图像背景抑制滤波算法研究

摘要

The features of infrared image is analyzed,including generating process and theory, general features,the features of background,target and noise,mathematical description. For different features,four algorithms,median filtering algorithm,wiener filtering algorithm,Butterworth high-pass filtering algorithm,Top-hat filtering algorithm are studied. Through software programming,four filtering functions are realized.%从红外图像的产生过程及原理,红外图像的特点,红外图像背景、目标和噪声的特征以及红外图像的数学描述等方面对红外图像进行特征分析.针对不同背景的红外图像特点,研究了中值滤波算法、维纳滤波算法、巴特沃斯高通滤波算法、基于Top-hat算子的滤波算法.通过软件编程,实现了针对不同背景的红外图像的4种滤波功能,并对所处理后的图像开展了滤波效果的评价研究.
