摘要
本文从物理学中的万有引力得到启发 ,提出了“引力分类法”。即假设任意样本与待定点存在着万有引力 ,根据引力的大小使待定点属于不同的类 ,从而达到分类的目的。并且通过对武汉城区的TM 3、4、5波段遥感影像数据进行监督分类的试验 ,初步证明了该分类方法的可行性。
This paper is inspired by the mind of universal gravitation and the method of 'gravitation classification' is introduced here. Assuming that universal gravitation exists between samples and any unknown point, this point can belong to a certain classification of the samples according to the law of universal gravitation. Through supervised classification of remote sensing image of urban area of Wuhan by TM (band 3,4,5), it has proved elementarily that such kind of classification is reasonable.
