Abstract:

A method of filtering hyperspectral image data associated with a hyperspectral image to produce a detection image data having a plurality of pixels, where the detection image data is associated with the degree to which a target may be present in a pixel. The method also includes adaptively processing the detection image data to determine a background variation in the plurality of pixels. The method additionally includes establishing a plurality of spatial filters for the detection image data, where each of the plurality of spatial filters are associated with energy being received at different locations on each of the plurality of pixels, and where the outputs of the plurality of spatial filters are weighted by the variation in background. The method further includes applying each of the plurality of spatial filers to the detection image data, such that each of the plurality of pixels are associated with a selected one of the plurality of spatial filters.
