This paper describes the Hyper-Spectral Imaging (HSI) scanner developed at IFAC-CNR for non-invasive diagnostics and accurate color acquisitions on paintings. This latter HSI application is still rare in the art conservation field due to the difficulties related to obtaining accurate, reliable, and reproducible data suitable for matching the colorimetric calculations as required by the Commission Internationale de l'Eclairage (CIE) for calibrated sRGB images and colorimetric values are presented. In the present paper, HSI measurements focused on color evaluation of color standards in laboratory and of a 15th century panel painting are reported.

Abstract
This paper describes the Hyper-Spectral Imaging (HSI) scanner developed at IFAC-CNR for non-invasive diagnostics and accurate color acquisitions on paintings. This latter HSI application is still rare in the art conservation field due to the difficulties related to obtaining accurate, reliable, and reproducible data suitable for matching the colorimetric calculations as required by the Commission Internationale de l'Eclairage (CIE) for calibrated sRGB images and colorimetric values are presented. In the present paper, HSI measurements focused on color evaluation of color standards in laboratory and of a 15th century panel painting are reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
