近红外高光谱成像技术对鸡蛋种类的鉴别
The identification of egg varieties by near infrared hyperspectral imaging technology
摘要
Abstract
In order to explore the feasibility of the near-infrared hyperspectral imaging technique of egg types,the samples were identified by near-infrared hyperspectral (900 ～ 1700 nm),among 223 egg samples,74 were selenium-enriched eggs,72 eggs were pollution-free eggs,77 of ordinary eggs for the study object.Selenium-enriched eggs and pollution-free eggs were the Hy-line brown eggs,and ordinary eggs were the organic eggs.Contrast Savitzky-Golay (SG)smoothing,Baseline,Standard Normal Variable (SNV),Normalize,preferred SG convolution smooth spectrum preprocessing method.The number of characteristic wavelengths extracted by Successive Projection Algorithm (SPA),Uninformative Variable Eliminatio (UVE),Backward interval PLS (BiPLS) was 8,107 and 155,respectively.PLS-DA discriminant models of full spectrum,SPA,UVE and BiPLS were established respectively,the results showed that the recognition performance of BiPLS-PLS-DA was better than the whole FS-PLS-DA,UVE-PLS-DA and SPA-PLS-DA in the four models,and the correct recognition rate was 95.24％,the prediction rate was 78.18％.Near-infrared hyperspectral imaging technology as a fast and efficient type of discrimination technology to determine the type of eggs is feasible.关键词
