Development of Discriminant Models for Wooden Breast Based on Visible and Near Infrared Hyperspectral Information and Their Fused Data

  • 摘要: 木質化雞胸肉(wooden breast,WB)制約肉雞行業發展,傳統觸診檢測方法耗時且效率低,為提升高光譜成像(hyperspectral imaging,HSI)技術檢測雞胸肉木質化程度的效果,本論文以白羽雞雞胸肉為研究對象,將其劃分4個木質化等級,采集其在400~1000和1000~2000 nm內的HSI信息,通過不同光譜預處理算法和特征波段篩選方法,建立基于全波段、特征波段和HSI數據融合的偏最小二乘判別分析(Partial least squares-discriminant analysis,PLS-DA)模型和支持向量機(Support vector machine,SVM)模型。結果顯示,SVM模型比PLS-DA模型更適于判別雞胸肉木質化程度,基于1000~2000 nm內全波段和特征波段的最佳模型預測集總體正確率均高于400~1000 nm內的模型,基于兩波段HSI數據融合的木質化判別模型優于基于單一波段(包括全波段和特征波段)的模型,最佳模型預測集總體正確率為96.7%,能較好地區分出4個木質化等級,且對4個等級的判別準確率均可達90%以上。研究結果為HSI實現木質化雞胸肉的準確無損檢測提供技術支持。

     

    Abstract: Wooden breast barriers the development of broiler industry, and traditional detection methods are time-consuming and inefficient. To investigate the feasibility of the hyperspectral imaging (HSI) technique for the detection of wooden breasts, four different grades of white feather chicken breast were selected and their HSI information of 400~1000 and 1000~2000 nm was collected. After spectral preprocessing and spectral variable selection, partial least squares discriminant (PLS-DA) models and support vector machine (SVM) models were developed based on full wavelength and characteristic spectral variables, as well as their fused HSI data. The results showed that SVM models showed better results than PLS-DA models to discriminate woody grades of chicken breasts. The overall discrimination rates based on the full HSI bands and selected spectral variables in 1000~2000 nm were higher than those of models in 400~1000 nm. Besides, the discrimination models based on fused HSI data of HSI bands and selected spectral variables provided the best results, with the overall discrimination rate of 96.7% for four different woody grades, and the accuracy of the four grades could reach more than 90%. The research results provided technical support for HSI to achieve rapid and non-destructive detection of wooden chicken breasts.
