SABS can be improved by SAFU for Hyperspectral imageries. The proposed SAFU selects the sets of uncorrelated hyperspectral bands for each different class simultaneously while utilizing the inherent separability of different classes in hyperspectral images to reduce dimensionality and further to effectively generate a unique SAFU feature. The experimental results show that the SAFU approach is effective and can be used as an alternative to the existing feature extraction algorithms.

本文提出的SAFU选取不同类别抽取出不同的波段，同时地利用不同类别在高光谱影像中固有的分离性来缩减维度及更进一步地有效产生一个独特的SAFU特徵，最后实验列举了一些分类正确率有不错表现的分类器与PBF分类器进行一些正确率的比较，实验的结果显示SAFU方法是有效且能够被当作目前现有的特徵萃取演算法中的其中一种。
