脐橙VC含量近红外光谱消噪小波优化（Wavelet Optimization for Near-infrared Spectra Denoising of Vitamin C Content of Umbilical Orange）
脐橙 近红外光谱 小波基
2009/5/22
运用db1～db10等10个小波基4尺度分解对120个赣州脐橙样品的近红外光谱进行消噪处理，分别建立了各种小波消噪光谱的脐橙维生素C(VC)含量的PLS模型。通过PLS模型预测精度比较表明：所有db小波基变换都能有效消除脐橙VC近红外光谱噪声，PLS模型预测精度均高于不处理光谱建立的模型预测精度。其中，消噪效果最好的小波基是db5，模型预测值与实测值的相关系数R达到0.9427、内部交叉验证均方差...
