In this paper we report some key questions related to the acquisition of accurate color images adressed by the Colour and Space in Cultural Heritage (COSCH) project. We summarize the main criteria defined by COSCH Working Group 1 and used by the authors to help Digital Cultural Heritage (DCH) users to have a deepen knowledge and understanding of the constraints, preconditions and practical aspects related to the use of a multi-spectral acquisition system. We also report how color data can be estimated from spectral data and discuss several issues related to the measurement of reflective surfaces by 2D imaging systems.

Abstract
In this paper we report some key questions related to the acquisition of accurate color images adressed by the Colour and Space in Cultural Heritage (COSCH) project. We summarize the main criteria defined by COSCH Working Group 1 and used by the authors to help Digital Cultural Heritage (DCH) users to have a deepen knowledge and understanding of the constraints, preconditions and practical aspects related to the use of a multi-spectral acquisition system. We also report how color data can be estimated from spectral data and discuss several issues related to the measurement of reflective surfaces by 2D imaging systems.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
