Discrimination of tobacco varieties using vis/near infrared spectra by wavelet transform and back propagation neural network model
Published 2009-11-01Get full textIn order to discriminate quickly varieties of tobacco samples based on vis/near infrared spectroscopy, principal component analysis (PCA) was used to analyze qualitatively the clustering of tobacco samples, and the data compressed by wavelet transform (WT) combined with artificial neural network (AN...

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...

Identification of crop and weed in seedling stage based on multi-spectral images
Published 2008-07-01Get full textAs machine vision owns many merits, 3CCD multi-spectral camera was used to capture pictures of soybean and two common weeds (Alternanthera philoxeroides and Eleusine indica). Based on the image from IR channel of multi-spectral images and the usage of segmentation and morphological processing, the s...
