In this paper, well-known traditional band selection methods which are used in hyperspectral imaging, namely, Maximum-Variance Principal Component Analysis (MVPCA), Maximum-SNR Principal Component Analysis (MSNRPCA), k-means, k-medoids, and recently proposed Automatic Band Selection (ABS) and Band Column Selection (BCS) approaches are compared. To assess the band selection performance of the methods, the change of classification performance by the number of selected bands is used. Performances of the methods are evaluated on three hyperspectral data sets and obtained results are compared in this paper.
