Detection of Early Bruises in Honey Peaches Using Shortwave Infrared Hyperspectral Imaging

August 01, 2022

By extracting the RGB, HSI, and grayscale information from a spectral range of 400–1100 nm and comparing the spectral features of sound and bruised peaches, the authors provided a classification system and theoretical basis for online fruit bruise detection.

Quantification of the Soluble Solids Content of Intact Apples by Vis–NIR Transmittance Spectroscopy and the LS-SVM Method

September 01, 2013

The feasibility of quantifying the soluble solids content of intact apples was investigated by visible and near infrared (vis–NIR) transmittance spectroscopy combined with the least squares support vector machines (LS-SVM) method. The spectra were pretreated by Savitzky-Golay smoothing, first and second derivatives, standard normal variate transformation, and multiplicative scatter correction.
