Abstract:
1. A method for detecting materials in a hyperspectral scene containing a plurality of pixels, the method comprising: in a detecting engine provided with a plurality of reference spectrums each of which includes spectral bands and a spectrum representative of a material, for each reference spectrum of a respective material: determining a kernel vector of detection filter weights containing an element for each spectral band of a subject reference spectrum; determining, based on the kernel vector for the subject reference spectrum, a detection filter score for each of the plurality of pixels and subject reference spectrum, the detection filter score being indicative of a likelihood the spectrum of a respective pixel matches the subject reference spectrum associated with the respective material; comparing the detection filter scores to a threshold; and determining, based on the comparison, in which of the plurality of pixels in the hyperspectral scene the respective material is present.
