The estimation of differential quantities on oriented point cloud is a classical step for many geometry processing tasks in computer …

Keynote speaker at DGCI 2016, Nantes.

This paper presents several methods to estimate geometric quantities on subsets of the digital space Zd. We take an interest both on …

The Voronoi covariance measure (VCM) of a compact set K of $\mathbb{R}^d$ is a tensor-valued measure that encodes geometrical …

We propose a robust estimator of geometric quantities such as normals, curvature directions and sharp features for 3D digital surfaces. …

In this paper, we introduce a new curvature estimator along digital contours, which we called global min-curvature (GMC) estimator. As …

Estimating curvature on digital shapes is known to be a difficult problem even in high resolution images. Moreover the presence of …
