卫星遥感技术在我国经济和社会发展及国防建设中得到了广泛的应用,并发挥了不可或缺的作用。随着遥感技术应用的深入发展,应用部门对遥感信息质量的要求也日益提高。因此,对遥感影像色彩通过各种手段进行改善,解决遥感影像在色彩方面的问题,成为当今急需解决的问题。
图像色彩增强技术作为遥感图像处理的一种重要手段,可以有效地改善遥感图像的视觉效果,增强信息的识别率,实现遥感应用质量的显著提高。基于此,本文在深入分析彩***像增强理论、图像的RGB彩色模型、图像的HSI彩色模型以及这两种模型相互转换原理及方法的基础上,重点阐述了怎样利用MATLAB软件,对彩***像HSI模型下的三个不同分量色调H、饱和度S、亮度I,分别通过色调增强、饱和度增强、直方图均衡化三种不同方法进行处理,从而达到遥感图像彩色增强的目的。

Abstract
Satellite remote sensing technology has a wide application and plays an indispensable role in the economic development, social development of our country, and our national defense construction. With the deepening of its application, the requirement for the quality of remote sensing information is continually improved. Therefor, to improving the color of the remote sensing image through varieties of means has been a urgent problem to be solved.
As an important means for remote sensing image processing, color enhancing technique can effectively improve the visual effect of the image, enhance the recognition rate of information, and evidently improve the quality of remote sensing application. According to the color enhancing theory, the function characteristics of RGB, HSI color models, and the transition method and theory between the two color models, the paper mainly discussed how to use the tonal enhancement method, the saturation enhancement method and the histogram enhancement method to test with H, S, I, ponent of the HSI color model, then to reach the purpose of enhancing the color of remote sensing image. Analysis was carried out using MATLAB.
