Decoupling actions of finite-dimensional Lie groups and of groups of diffeomorphisms in the large deformation framework
Rayane Mouhli, Thomas Pierron
In computational anatomy, the Large Deformation Diffeomorphic Metric Mapping (LDDMM) framework has become a central tool for modeling smooth, invertible transformations between sha…

Barycentric subspace analysis of network-valued data
Elodie Maignant, Xavier Pennec, Alain Trouvé +1
Certain data are naturally modeled by networks or weighted graphs, be they arterial networks or mobility networks. When there is no canonical labeling of the nodes across the datas…

The graded group action framework for sub-riemannian orbit models in shape spaces
Thomas Pierron, Alain Trouvé
In the standard orbit model on shape analysis, a group of diffeomorphism on the ambient space equipped with a right invariant sub-riemannian metric acts on a space of shapes and in…
