The link between Bayesian and variational approaches is well known in the image analysis community in particular in the context of
deformable models. However, the current trend is the computation of statistics mainly based on PCA analysis or non-linear extension on
manifold using local linearization through the exponential mapping. We will try to show in talk that going from statistics to statistical
modelling in the context of deformable models leads to interesting new questions, mainly unsolved, about the statistical
modelling itself but also about the derivation of consistent and effective estimation algorithms.
