| 摘 要： | 在研究比较了ICA(独立成分分析)和PCA(主成分分析)方法的差异后,借鉴PCA提取遥感蚀变信息的应用方法,应用ICA的原理,提出了一种基于ICA的遥感蚀变信息提取方法.以ICA方法替代传统的PCA方法,进行遥感矿物蚀变信息提取实验.并以哈图金矿矿区为例,分别用ICA和PCA方法对ETM+影像提取羟基蚀变信息和铁染蚀变...

| Abstract: | This paper analyses the algorithm of ICA(Independent Component Analysis) and compares its differences with PCA(Principal Component Analysis) algorithm,then presents a method to extract alteration information of miner from remote sensing data based on ICA.The method which is different from the traditional method used by PCA is used by ICA to extract alteration information.PCA,used widely in geological prospecting industry,is multivariate data processing method based on second order statistics methods on sign... |
