1. A system comprising:
at least one hardware processor; and
a non-transitory computer-readable storage medium having stored thereon program instructions, the program instructions executable by the at least one hardware processor to:
receive, as input, spectral image data representing spectral reflectance associated with at least one plant,
calculate a first chlorophyll fluorescence index in a first wavelength band, and a second chlorophyll fluorescence index, in a second wavelength bands, based, at least in part, on said spectral reflectance, and
derive 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.
