以云南省宜良县ALOS影像为基础数据,利用最大似然法、支持向量机方法和面向对象的支持向量机方法对ALOS影像进行植被分类研究。实验结果最大似然法分类精度为79.33%,支持向量机方法分类精度为82.25%,面向对象的支持向量机分类方法精度为86.13%,面向对象的支持向量机分类方法取得较好的分类效果。研究结果可为中高分辨率遥感影像分类研究提供参考。

Based on the data of ALOS image of Yiliang County,Yunnan Province,this paper discusses the use of the maximum likelihood method,support vector machine method and object-oriented support vector machine(SVM).The results show that maximum like-lihood classification accuracy is 79.33%,SVM classification accuracy 82.25%,oriented object based support vector machine classification accuracy 86.13%,and oriented-object based support vector machine classification method has better classification results.The results can provide a reference for the study of high-resolution remote sensing image classification。
