Claim 12:
13. A method for execution by a sensor system, the method comprising:
receiving, by an optical sensor array, incident light radiation associated with a scene, wherein the optical sensor array includes a plurality of optical sensors, wherein an optical sensor of the plurality of optical sensors is associated with an optical filter of a plurality of sets of optical filters and each optical filter of a set of optical filters is configured to pass light in a different wavelength range;
outputting, by the optical sensor array, information representative of the incident light radiation;
generating, based on the information representative of the incident light radiation, by first processing circuitry operably coupled to the optical sensor array, a plurality of spectra, wherein each spectrum of the plurality of spectra is associated with a set of optical filters;
determining, based on the plurality of spectra, by first processing circuitry, a plurality of error coefficients, wherein an error coefficient of the plurality of error coefficients is representative of a difference between a generated spectrum and a target spectrum for a set of optical filters;
training, by second processing circuitry, an artificial neural network based on the plurality of error coefficients;
classifying, by the artificial neural network, the plurality of spectra to produce an illuminant spectrum associated with each set of optical filters.
