A sub-Riemannian modular approach for diffeomorphic deformations
Participants : Barbara Gris [Correspondant] , Stanley Durrleman, Alain Trouvé.
We develop a generic framework to build large deformations from a combination of base modules. These modules constitute a dynamical dictionary to describe transformations. The method, built on a coherent sub-Riemannian framework, defines a metric on modular deformations and characterises optimal deformations as geodesics for this metric. We present a generic way to build local affine transformations as deformation modules, and display examples.
