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.

本篇论文提出一个新型的模拟退火特徵齐一化波段选取法应用在高光谱遥测影像的特徵萃取，模拟退火波段选取法已经成功的应用在高光谱影像的特徵萃取藉著群集高度相关的高光谱波段将之形成一个基於模拟退火演算法波段模组的子集合，本文提出之SAFU是建立在SABS之上，利用旧有SABS的特性加以改良，提出SAFU来对於高光谱影像可以更有效率的进行特徵萃取。
