Inspect Rice Seed Vigor of Conventional Rice by Hyperspectral Imaging with Chemometric Methods
摘要
Abstract
[Objective]The aim was to realize fast and automatic dection of rice seed vigor.[Method]Hyperspectral imaging covering the spec-tral range of 874-1734 nm was applied to detect conventional rice seed vigor.Two rice seed cultivars ( named Yongxian69 and Zhongzao 39) were used for analysis.Spectral information of untreated rice seeds, rice seeds accelerated aging for 48 hours and 72 hours was extracted from hyperspectral images.Wavelet transform was applied to eliminate obvious random noises of pixel-wise spectra before spectra extraction.Sup-port vector machine (SVM) was applied to build discriminant models using full spectra.The SVM models of the two rice cultivars showed ac-ceptable results.[ Result] The untreated seeds and treated seeds could be accurately discriminated , while seeds accelerated aging for 48 hours and 72 hours could not be discriminated.The results matched with the vigor test by traditional methods, and the accelerated aging showed differences on different seed cultivars.[Conclusion]The hyperspectral imaging combined with chemometric methods could be used for fast, automatic and non-invasive detection of rice seed vigor.关键词
