Paper Abstract

In this paper, we investigate the use of linear filtering techniques in the exploitation of hyperspectral imagery. In particular, we focus on applications of the simultaneous diagonalization (SD) filter to hyperspectral image analysis. The SD filter can be designed to enhance a particular feature with a known spectral response pattern and suppress undesired features. The filter is used to enhance surface features in two AVIRIS scenes acquired from the Forest Ecosystem Dynamics (FED) flightline on September 8, 1990. A spectral distance algorithm is also applied to this hyperspectral data to enhance surface targets with similar spectral response patterns. Although no detailed ground information was utilized, targets were selected by image interpretation methods and included an urban/disturbed site, and a wetland bog area, and a northern vegetation type (mixed hardwood). Both the SD filter and the spectral distance algorithm are able to effectively separate these classes of ground features from others.
