On triangle meshes with valence dominant vertices
Jean-Marie Morvan
We study triangulations defined on a closed disc satisfying the following condition: In the interior of , the valence of all vertices of except one of them…
Improving Shadow Suppression for Illumination Robust Face Recognition
Wuming Zhang, Xi Zhao, Jean-Marie Morvan +1
2D face analysis techniques, such as face landmarking, face recognition and face verification, are reasonably dependent on illumination conditions which are usually uncontrolled an…
Smooth Riemannian Structures on Dessins d'Enfants
Jean-Marie Morvan
We show how to define a canonical Riemannian metric on a "dessin d'enfants' drawn on a topological surface. This gives a possible explanation of a claim of A. Grothendieck.
Asymptotic Cones of Embedded Singular Spaces
Xiang Sun, Jean-Marie Morvan
We use geometric measure theory to introduce the notion of asymptotic cones associated with a singular subspace of a Riemannian manifold. This extends the classical notion of asymp…
