In this paper we investigate the combined use of morphological attribute filters and feature extraction techniques for the classification of a high resolution hyperspectral image. In greater detail, we propose to model the spatial information with Extended Attribute Profiles computed on the hyperspectral data and to reduce the high dimensionality of the morphological features computed (which show a high degree of redundancy) with feature extraction techniques. The features extracted are analyzed by two classifiers. The experimental analysis was carried out on a high resolution hyperspectral image acquired by the airborne sensor ROSIS-03 on the University of Pavia, Italy. The obtained results compared to those obtained without feature reduction proved the importance of the application of a stage of feature extraction in the process.

Abstract

In this paper we investigate the combined use of morphological attribute filters and feature extraction techniques for the classification of a high resolution hyperspectral image. In greater detail, we propose to model the spatial information with Extended Attribute Profiles computed on the hyperspectral data and to reduce the high dimensionality of the morphological features computed (which show a high degree of redundancy) with feature extraction techniques. The features extracted are analyzed by two classifiers. The experimental analysis was carried out on a high resolution hyperspectral image acquired by the airborne sensor ROSIS-03 on the University of Pavia, Italy. The obtained results compared to those obtained without feature reduction proved the importance of the application of a stage of feature extraction in the process.
