Within the first call for proposals by NICAS (Netherlands Institute for Conservation, Art and Science), six full proposals and five seed money proposals have been granted. Marjan Sjerps is co-applicant of the awarded seed proposal "Value of evidence".
The project leader of "Value of evidence" is dr. Maartje Stols-Witlox of the Faculty of Humanities. The research team is formed by five researchers of the University of Amsterdam and employees from the Van Gogh Museum and the Rijksmuseum Amsterdam.
To answer questions about authenticity and age of artworks, art historians nowadays have access to a multiplicity of techniques. In addition to the analysis of the style used and archive research, also X-ray imaging, isotopes research and other optical techniques provide information about a work of art. But what information is most important? The researchers use a technique used in mathematics, Bayesian networks, in order to quantify the value of each piece of evidence.
