COLLOQUE DU DIRO --- http://www.iro.umontreal.ca/~csuros/ColloquesDIRO/http://www.iro.umontreal.ca/%7Ecsuros/ColloquesDIRO/

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. ------------------
