WebHyperspectral images were acquired from a total of 1,680 Fusarium-infected wheat head samples over a wavelength range of 400-1000 nm. The principal component analysis was used to reduce dimension of the hyperspectral image. The central wavelengths at 660, 560 and 480 nm were combined into the RGB image and then transferred to YDbDr space.
