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.
