Otolith are small stone growing according to an accretionary process located in fishes inner ears from which a lot can be learnt about their biology and ecology. Computer vision is one of the mean of systematic analysis of those stone. This paper describe an approach using partial differential equation and variational methods to reconstruct the morphogenesis of an otolith from an image.
Résumé
Les otolithes sont de petites concrétions calcaires situées dans l'oreille interne des poissons qui peuvent nous en apprendre beaucoup sur leur biologie et leur écologie. La vision par ordinateur est l'une des méthodes d'analyse systématique possible. Nous présentons ici une approche à base d'équation aux dérivées partielles et de méthodes variationnelles permettant de reconstituer la morphogénèse d'un otolithe à partir d'une image.
