| 2 | Nondestructive classification of mung bean seeds by single kernel near-infrared spectroscopy显示文摘Near-infrared spectroscopy(NIRS)in the range 900-1700 nm was performed to develop a clas-sifying model for dead seeds of mung bean using single kernel measurements.The use of the combination of transmission-absorption spectra and refection-absorption spectra was deter-mined to yield a better classification performance(87.88%)than the use of only transmission-absorption spectra(81.31%).The effect of the orientation of the mung bean with respect to the light source on its absorbance was investigated.The results showed that hilum-down orientation exhibited the highest absorbance compared to the hilum-up and hilum-parallel-to-ground orientations.We subsequently examined the spectral information related to the seed orientation by developing a classifying model for seed orientation.The wavelengths associated with classi-fication based on seed orientation were obt ained.Finally,we determined that the re-developed classifying model excluding the wavelengths related to the seed orientation afforded better ac-curacy(89.39%)than that using the entire wavelength range(87.88%). | Kaewkarn Phuangsombut Nattaporn Suttiwijitpukdee Anupun Terdwongworakul | 2017 | Journal of Innovative Optical Health Sciences2017，，3： | 0 |
