The Effect of Sub-sampling on Hyperspectral Dimension Reduction

Abstract

Hyperspectral images which are captured in narrow bands in continuous manner contain very large data. This data need high processing power to classify and may contain redundant information. A variety of dimension reduction methods are used to cope with this high dimensionality. In this paper, the effect of sub-sampling hyperspectral images for dimension reduction techniques is explored and compared in classification performance and calculation time. © Springer International Publishing Switzerland 2013.
