Research on Products Quality Stability Based on Near Infrared Spectroscopy and Feature Extraction of PCA Radar Chart
and lack of visual results show of the quality monitoring of cigarette products
the near infrared spectroscopy analysis techniques were applied to the process of product stability control and a new feature extraction method of the fingerprint spectrum was presented. Firstly
the principal component analysis method was used for the dimension reduction of the near infrared (NIR) spectra
and the radar chart was employed for the visual description of the quality stability trends of the products. This ensures the unification of integrity and fuzziness of the spectra data. And then
the barycentre features of the radar chart were extracted
which realized the demonstration of the internal structure of the samples. Also the model of the quality stability and the abnormal type was established. The study shows that this feature extraction method achieves desired result and can be used in the quality monitoring and counterfeit identification of the cigarette products.
