Claim 10:
11. A method comprising:
receiving, as input, spectral image data representing spectral reflectance associated with at least one plant;
calculating a first chlorophyll fluorescence index in a first wavelength band, and second chlorophyll fluorescence index in a second wavelength band, based, at least in part, on said spectral reflectance; and
deriving a quantum yield value with respect to said at least one plant, by:
(i) dividing said first chlorophyll fluorescence index in a sum of said first chlorophyll fluorescence index and said second chlorophyll fluorescence index, and
(ii) multiplying (i) by a vegetation index value associated with said at least one plant.
