Determination of rice leaf blast disease level based on visible-near-infrared spectroscopy
Published 2011-05-01Get full textA rapid determination of rice leaf blast disease based on visible-near-infrared spectroscopy was proposed. Chemometric analysis was executed on the spectra of the rice leaves with different disease level by using partial least square regression (PLSR). Three PLSR models were established based on ful...
