Workshop sur la complexité spatio-chromatique (CIE TC 8-14)
Nous organisons dans le cadre de MIRES, des journées de travail sur la définition et la mesure de la complexité spatio-chromatique des surfaces colorées planes les 10, 11 et 12 Juillets prochains.
La mesure de la complexité spatio-chromatique donne un cadre pour le développement de la métrologie de l’aspect texturé/non-uniforme des surfaces colorées. Le propos intègre à la fois des questions de mathématique (dimension fractale dans des espaces de dimension n), de synthèse de textures, d’analyse d’images et de physique. L’ensemble se développe dans un contexte reliant le domaine perceptuel (mesures trichromatiques et expérimentation psycho-physique) et le domaine physique (mesures multi et hyperspectrales).
Les deux premiers jours se passeront à l’espace Mendes-FRance à Poitiers et la matinée du 12 au laboratoire XLIM(salle du troisième). Je vous ai joint le programme qui est encore mouvant sur certains horaires.
