摘要
为了解决灰度遥感影像对比度偏低的问题,以Matlab为平台,采用直方图的理论基础,直方图均衡化的概念及理论,对某地区遥感TM单波段遥感影像进行直方图均衡化的实验;并给出了具体程序、实验结果图像、直方图及变换函数。实验结果表明:原来偏暗且对比度较低的图像经过直方图均衡化后对比度及平均亮度明显提高,直方图均衡化处理能有效改善灰度图像的对比度差和灰度动态范围;该算法是一种行之有效的图像增强算法。
In order to solve the problem of low contrast of remote sensing image,do experiment for TM image of one area based on Matlab with the support of its theory;give the concretely procedure,experiment result image,histograms and transform function.The experiment show that the contrast and the average brightness of the image have been improved effectively,and adaption histogram equalization can improve image contrast and average brightness effectively.This method is an effective arithmetic.
