Use of near infrared hyperspectral tools for the screening of extractable polyphenols in red grape skins
(Elsevier, 2015)
Hyperspectral images of intact grapes were recorded at harvest time using a near infrared hyperspectral imaging system (900–1700 nm). Spectral data have been correlated with red grape skin extractable poly- phenols (total ...

Comparative study on the use of anthocyanin profile, color image analysis and near-infrared hyperspectral imaging as tools to discriminate between four autochthonous red grape cultivars from la Rioja (Spain)
(Elsevier, 2015)
Three independent methodologies were investigated to achieve the differentiation of red grapes from different grape varieties (Garnacha, Graciano, Mazuelo and Tempranillo) collected from five vineyards located in the ...

Simplified method for the screening of technological maturity of red grape and total phenolic compounds of red grape skin: Application of the characteristic vector method to near-infrared spectra
(American Chemical Society, 2015)
Characteristic vector analysis has been applied to near-infrared spectra to extract the main spectral information from hyperspectral images. For this purpose, 3, 6, 9, and 12 characteristic vectors have been used to ...
