Texto completo da fonteThis thesis develops Geometric Statistics to analyze the normal andpathological variability of organ shapes in Computational Anatomy. Geometricstatistics consider data that belong to manifolds with additional geometricstructures. In Computational Anatomy, organ shapes may be modeled asdeformations of a template - i.e. as elements of a Lie group, a manifold with agroup structure - or as the equivalence classes of their 3D configurations underthe action of transformations - i.e. as elements of a quotient space, a manifoldwith a stratification. Medical images can be modeled as manifolds with ahorizontal distribution. The contribution of this thesis is to extend GeometricStatistics beyond the now classical Riemannian and metric geometries in orderto account for these additional structures. First, we tackle the definition ofGeometric Statistics on Lie groups. We provide an algorithm that constructs a(pseudo-)Riemannian metric compatible with the group structure when itexists. We find that some groups do not admit such a (pseudo-)metric andadvocate for non-metric statistics on Lie groups. Second, we use GeometricStatistics to analyze the algorithm of organ template computation. We show itsasymptotic bias by considering the geometry of quotient spaces. We illustratethe bias on brain templates and suggest an improved algorithm. We then showthat registering organ shapes induces a bias in their statistical analysis, whichwe offer to correct. Third, we apply Geometric Statistics to medical imageprocessing, providing the mathematics to extend sub-Riemannian structures,already used in 2D, to our 3D images

Texto completo da fonteIn this thesis, we study data analysis algorithms using random walks on neighborhood graphs, or random geometric graphs. It is known random walks on such graphs approximate continuous objects called diffusion processes. In the first part of this thesis, we use this approximation result to propose a new soft clustering algorithm based on the mode seeking framework. For our algorithm, we want to define clusters using the properties of a diffusion process. Since we do not have access to this continuous process, our algorithm uses a random walk on a random geometric graph instead. After proving the consistency of our algorithm, we evaluate its efficiency on both real and synthetic data. We then deal tackle the issue of the convergence of invariant measures of random walks on random geometric graphs. As these random walks converge to a diffusion process, we can expect their invariant measures to converge to the invariant measure of this diffusion process. Using an approach based on Stein's method, we manage to obtain quantitfy this convergence. Moreover, the method we use is more general and can be used to obtain other results such as convergence rates for the Central Limit Theorem. In the last part of this thesis, we use the concept of persistent homology, a concept of algebraic topology, to improve the pooling step of the bag-of-words approach for 3D shapes

Texto completo da fonteSome datasets exhibit non-trivial geometric or topological features that can be interesting to infer.This thesis deals with non-asymptotic rates for various geometric quantities associated with submanifolds M ⊂ RD. In all the settings, we are given an i.i.d. n-sample with common distribution P having support M. We study the optimal rates of estimation of the submanifold M for the loss given by the Hausdorff metric, of the reach τM, of the tangent space TX M and the second fundamental form I I MX, for X ∈ M both deterministic and random.The rates are given in terms of the sample size n, the instrinsic dimension of M, and its smoothness.In the process, we obtain stability results for existing reconstruction techniques, a denoising procedure and results on the geometry of the reach τM. An extension of Assouad's lemma is presented, allowing to derive minimax lower bounds in singular frameworks
