摘要
介绍了高光谱遥感的发展概况及通用数据处理流程,着重分析了数据处理过程中的Hughes现象,指出可以通过对传统的处理方法进行适当的改进来有效地抑制Hughes现象,提高高光谱影像分类精度。
Hyper-spectral images have been used to gather the data about the earth's surface since 1970s.From the very beginning,lots of attentions have been given to this kind of images because of the higher spectral resolution.This paper introduced the development of the hyper-spectral remote sensing and the common processing technique,and then focused on analyzing the Hughes phenomenon,which might occur frequently during the process.The author indicated that the Hughes phenomenon could be mitigated when additional processing steps had been performed.As a result,an improvement in classification accuracy had been achieved.
