摘要
介绍了目前遥感影像分类的常用方法,提出了一种基于知识的信息提取的遥感影像模糊分类方法。采用GIS数据辅助进行遥感影像模糊法分类,从GIS数据库中提取一定数量的样本信息或挖掘知识形成规则,进行样本的训练学习或辅助进行分类判定。提高了分类的效率和精度,是对模糊分类方法一次有效改进。
The method used for GIS data supporting fuzzy image classification act was presented here. Rules were formed by extracting a certain number of sample information or excavating knowledge from GIS database, carrying out the study or training of samples or the auxiliary classification determination that increase the efficiency and precision, and was an effective improvement of fuzzy classification method.
