菜籽品种可见近红外光谱鉴别研究
Discrimination varieties of vegetables' seeds by visible near infrared spectroscopy
摘要
Abstract
The seed varieties of vegetable are one of the major factors that decide the quality of the vegetables. A discrimination method of vegetables' seeds by visible and near-infrared speetroscopy (Visible-NIR) was proposed for rapid discriminating the varieties of vegetables' seeds. The spectra of six vegetables' seeds were collected by reflection mode in the range of 400 ~1 000 nm. Seventeen variables were chosen by curve peak and valley trends of principal components loadings. And linear discrimination analysis (LDA) models were developed with the input vectors of seventeen variables. The discriminating results of LDA models were superior to the principal component analysis (PCA) with the error recognition rate of 2.42%. The results suggest it is feasible for rapid discrimination varieties of vegetables' seeds by visible-NIR technology and LDA method.关键词
