基于SA4向量小波变换及Fisher算法的红外弱小目标检测
Small Weak Infrared Target Detection Based on SA4 Multiwavelet Transform and Fisher Algorithm
【摘要】 本文提出了一种新的红外图像弱小目标检测方法,即利用SA4向量小波的优良性质,采用恰当的预滤波器对图像进行预处理;而后利用Fisher算法对经SA4向量小波变换得到的高频图像进行分割,最终将目标从背景中分离出来。大量实验表明该算法是有效的。
【Abstract】 This paper is aimed to suggest a new algorithm for detecting infrared targets. Utilizing the excellent quality of SA4 multiwavelet, an infrared image is firstly preprocessed with a proper pre-filter, then segmented by the Fisher algorithm, and finally the target Ocould be detected from the background. A large number of experiments indicate that the whole algorithm is quite effective.
