SPEC-2B Dataset: A Visible–Near Infrared (VIS–NIR) Reflectance Spectra of Blueberry Fruits Across Cultivars and Maturity Stages.
Listed in Repositorio de Datos de Investigación Universidad Andrés Bello
The SPEC-2B Dataset is an open collection of visible–near infrared (VIS–NIR) reflectance spectra acquired from blueberry (*Vaccinium corymbosum* L.) fruits representing multiple cultivars and visually assessed maturity stages.
Description
The dataset was created to support reproducible research in agricultural spectroscopy and optical sensing, with a focus on exploratory analysis, preprocessing evaluation, and spectral data characterization. **Version:** 2.0 This version introduces enhanced reproducibility and usability through: - Inclusion of raw spectral measurements and white reference data - Updated and fully reproducible preprocessing workflows - Revised visualization notebooks with improved usability - Extended documentation and data access instructions
