摘要
基于色彩合成原理的传统遥感图像增强手段存在很大的局限性,提出了一种直方图均衡化调整图像像素灰度值的方法,利用该方法对多光谱遥感图像进行增强处理,处理后的图像再进行彩色合成。实例分析表明,该方法直观、快捷,并能取得较好的视觉判读效果,具有一定的实用意义。
Remote sensing image color composite is a traditional means of remote sensing image enhancement based on the theory of color composite.So there are great limitations.A histogram equalization method was proposed for evaluating gray value for each pixel after histogram equalization.Multi-spectral remote sensing images were processed by this method,and then these improved images were changed into color composite images.The case analysis showed that this method was intuitive and effective,and it could acquire a better visual interpretation,and had some practicability.
