Reflectance spectra of winter wheat leaves specimens was acquired with portable spectroradiometer and integral sphere, after pretreatment with the method of multiplicative scatter correction(MSC), the principal components calculated were used as the inputs of artificial neural networks to build the Back--Propagation artificial neural networks model(BP-ANN),(More)
For biomaterial, the signal energy is concentrated at low frequencies, and then the first few Fourier coefficients can represent the whole spectrum. Fourier coefficients are useful wavelength reducing method. The first few Fourier coefficients of millet's near infrared diffuse reflectance spectroscopy were used as the input nodes of artificial neural(More)
