Français :
En géométrie discrète appliquée à l'imagerie nous essayons de développer une nouvelle géométrie qui s'applique aux pixels 2D et aux voxels 3D, 4D et de manière plus générale à toute dimension. Nous nous intéressons particulièrement aux modèles analytiques dans le monde discret c'est-à-dire à la définition mathématique d'objets discrets.

English:
In discrete geometry applied to imagery we try to develop a new geometry that can be applied to 2D pixels, 3D voxels and more generally to n-dimensional discrete objects. We are particularly interested in analytical models for the discrete world, which means that we are trying to propose mathematical definitions for discrete objects.
