Abstract
In this letter, we proposed a novel band selection algorithm for hyperspectral images (HSIs) based on column subset selection. The main idea of the proposed algorithm comes from the column subset selection problem in numerical linear algebra. It selects a group of bands, which maximizes the volume of the selected subset of columns. Since the high dimensionality decreases the contrast between bands, we use Manhattan distance to obtain a higher selection quality. Experimental results on real HSIs show that the proposed algorithm obtains competitively good results, in terms of classification accuracy, and is robust to noisy bands.
