Computational Imaging of Cultural Heritage

Because art is inherently visual, use of imaging has long been an important way to understand its structure, form, and history. Recently, new ways of engaging with objects from our shared cultural heritage are possible with advances in computation and imaging that allow scientists to analyze art non-invasively, historians to pose new social questions about the art, and the public to explore and interact with art in ways never before possible. This talk examines a number of computational imaging techniques that are currently being used to unlock the sequences of operations an artist may use to make a work of art. Also to be discussed is how one can better understand the deterioration of art materials over time using imaging.
