查询词典 extraction

In this regard, the research trend of globalization of competition has been positively open up. In this paper a novel simulated annealing feature uniformity band selection approach is proposed for the feature extraction of the hyperspectral remote sensing images. The simulated annealing band selection method has been successfully applied to the feature extraction of the hyperspectral images by clustering highly correlated hyperspectral bands into a smaller subset of band modules based on simulated annealing algorithm. SAFU built by SABS is an efficient feature extraction method.
