| 摘 要： | ISODATA算法是遥感影像非监督分类的典型算法之一。在进行非监督分类前，需要对遥感影像进行必要的处理，影像增强就是其中最为重要的步骤之一。本文通过对ISODATA算法和影像增强算法的阐述，分析了影像增强算法与非监督分类结合的方式和局限性。并通过实验分析了常用影像增强算法对非监督分类结果的影响，科学合理的选择适当的影像增强算法来提高非监督分类的可靠性。

| Abstract: | ISODATA algorithm is one of the typical algorithms for remote sensing image unsupervised classification .Image enhance-ment is one of the necessary steps before making unsupervised classification of remote sensing images .This article elaborates the ISO-DATA algorithm and image enhancement algorithms , and analyzes the limitation of combination of image enhancement algorithms with unsupervised classification methods .Experimental analysis by using image enhancement before unsupervised classification is conduc -ted to make a scientific and rational selection of appropriate image enhancement algorithms to improve the reliability of unsupervised classification. |
