从粗糙集角度提出了面向遥感影像及其分类的不确定性度量指标,包括遥感影像的不确定性度量,监督分类中样本数据质量的度量,这些指标的提出有利于研究遥感影像本身的不确定性,可用于指导遥感影像分类过程中的离散化方法选取、样本区的选取、分类器的选择等.
Uncertainty measure indices based on rough sets for remote sensing image and remote sensing image classification were introduced. The indices include the uncertainty measure of remote sensing image, the measure of quality of the sample data in supervised classification ,These measurements could facilitate to the research of the inherent uncertainty of the remote sensing image, conducting all the stages of the remote sensing image classification,such as selecting discretization algorithms,sample area data,classifiers and so on.
