digital topology

This paper proposes a set of tools to analyse the geometry of multidimensional digital surfaces. Our approach is based on several works …

In order to define consistent models and algorithms for image analysis, many topological representations of images have been proposed. …

Iso-surfaces are routinely used for the visualization of volumetric structures. Further processing (such as quantitative analysis, …

The definition and extraction of objects and their boundaries within an image are essential in many imaging applications. Classically, …

We design a new model for an image iso-surface which lies in the Delaunay graph of its vertices. Within each 8-cube of the image, a set …

This work highlights the relation existing between isosurfaces of an image with a given threshold (as classically computed by a …

In this article, we present a new process for defining and building the set of configurations of Marching-Cubes algorithms. Our aim is …
