Informational Aesthetic Measures and the Evolution of Van Gogh’s Artwork.

SibertConfLe jeudi 18 septembre, l’Imaginarium accueillera le Professeur Mateu Sbert (Univ. de Girona), à l’invitation du CNRS, pour un séminaire ouvert à tous publics.
Cette manifestation est organisée dans le cadre du programme de recherche Sciences et Cultures du Visuel, et bénéficie du soutien du CNRS et des Universités Lille 1 et Lille 3.

Le séminaire se déroulera au premier étage de l’Imaginarium (Tourcoing), dans le fonds documentaire, à partir de 16:00.

Informational Aesthetic Measures and the Evolution of Van Gogh’s Artwork.

In 1928, George D. Birkhoff introduced the Aesthetic Measure, defined as the ratio between order and complexity, and, in 1965, Max Bense analyzed Birkhoff’s measure from an information theory point of view. In this talk, the concepts of order and complexity in an image are analyzed in the light of information-theoretic measures and Kolmogorov complexity. The measures proposed are applied to several works. In particular, we analyze the evolution of van Gogh’s style towards the Auvers final period using some informational measures based on the entropy of the palette, the compressibility of the image, an information channel to capture the basic structure of the painting, and other entropy-based measures that take into account spatial information. The values of these measures match fairly well against the different styles in van Gogh’s work and allow a quantitative description of these periods. In addition, we present two measures which quantify the information associated with both color and canvas regions and enable us to visualize the most salient colors and elements of a painting.
