In this review, topic modeling—an unsupervised machine learning tool—is employed to
analyze research on pigments in cultural heritage published from 1999–2023. The review …

Hyperspectral imaging (HSI) has emerged as an effective tool to obtain spatially resolved
spectral information of artworks by combining optical imaging with spectroscopy. This …

Recently, many deep neural networks (DNN) have been proposed to solve the spectral
reconstruction (SR) problem: recovering spectra from RGB measurements. Most DNNs seek …
