Conférencier: David Stork (Ricoh Innovations et Stanford U.)
Titre:  Computer vision in the study of art: New rigorous approaches to the
study of paintings and drawings

Date: jeudi, le 19 novembre 2009, 15:30
Lieu: Salle 6214, Pavillon André-Aisenstadt

Résumé:

New rigorous computer algorithms have been used to shed light on a number of
recent controversies in the study of art. For example, illumination
estimation and shape-from-shading methods developed for robot vision and
digital photograph forensics can reveal the accuracy and the working methods
of masters such as Jan van Eyck and Caravaggio. Computer box-counting
methods for estimating fractal dimension have been used in authentication
studies of paintings attributed to Jackson Pollock. Computer wavelet
analysis has been used for attribution of the contributors in Perugino's
Holy Family and works of Vincent van Gogh. Computer methods can dewarp the
images depicted in convex mirrors depicted in famous paintings such as Jan
van Eyck's Arnolfini portrait to reveal new views into artists' studios and
shed light on their working methods. New principled, rigorous methods for
estimating perspective transformations outperform traditional and ad hoc
methods and yield new insights into the working methods of Renaissance
masters. Sophisticated computer graphics recreations of tableaus allow us to
explore what if scenarios, and reveal the lighting and working methods of
masters such as Caravaggio.
