Abstract
Hyperspectral image (HSI) classification is an important topic in remote sensing. In this paper, we propose a new method for HSI classification by using minimum noise fraction (MNF), spatial filtering (SF) and support vector machine (SVM). We use MNF to reduce the dimensionality of a hyperspectral data cube before performing classification. We apply 2D SF to the DR output band images and then use SVM to classify the pixels of the data cube. In this way, both spatial information and spectral information are taken into consideration in the classification. Experimental results show that our MNF+SF method is extremely competitive when compared to several existing classification methods.
