基于直方图调整和击中击不中变换的弱小目标检测

摘要

针对复杂背景图像中弱小目标像素少、灰度低,难于检测的问题,本文提出了一种基于直方图调整和数学形态学击中击不中变换相结合的弱小目标检测方法.该方法根据弱小目标的灰度特征,先对原始图像进行直方图调整,提高弱小目标的邻域信杂比,然后对二值化图像进行击中击不中变换,检测出可疑目标集合.实验结果表明,该方法能够有效地检测复杂背景下的弱小目标.%It is hard to detect the dim small target with few pixels and low intensity in the image of complex background.According to the intensity features of dim small target,a scheme based on histogram adjustment and hit-miss transform is presented to detect dim small target.In this method,histogram adjustment is adopted to enhance the signal-cluster-ratio,and hit-miss transform is used to get the suspicious targets.The experiment shows that the method is efficient in detecting dim small target with complex background.
