模糊掩模及其与传统掩模的关系

基于集合论方法构建了模糊掩模的数学模型，认为该模型是对传统掩模的一个扩展。与传统掩模主要用以解决空间混杂问题不同，模糊掩模侧重于解决波谱混杂问题。该方法利用波谱分离技术，通过对端元组分波谱丰度的求解，构建遥感图像的模糊子集，达到解决波谱混杂问题的目的。这两种掩模方法相结合，可为遥感图像的预处理提供更好的途径。

Fuzzy Masking and Its Relationships with Traditional Masking

A mathematical model of fuzzy masking was proposed based on the set theory,which was considered as expansion of the traditional masking.In contrast to the traditional masking which mainly focuses on the problems of spatial mixture,fuzzy masking mainly focuses on the problems of spectral mixture.In our fuzzy masking method,in order to resolve the problem of spectral mixture,spectra-separating technology is used to calculate abundances of the end-member spectra and to create fuzzy subsets of the remote sensing image.Fuzzy Masking method combined with traditional masking method,can provide a better solution for preprocessing of remote sensing imagery.
