Fig 6. False-colour compositions of visible and near infrared (VNIR) (503.5 nm, 660.1 nm, and 970.5 nm) and short wavelength infrared (SWIR) (1200.3 nm, 1759.2 nm, and 2202.3 nm) hyperspectral bands of an oilseed rape leaf inoculated with Alternaria alternata .

. The lower plot shows spectral characteristics within selected regions of the image representing the infected area, uninfected area, and entire leaf with standard deviation (std).
