Given a sample of an abstract manifold immersed in some Euclidean space, we describe a way to recover the singular homology of the original manifold. It consists in estimating its tangent bundle---seen as subset of another Euclidean space---in a measure theoretic point of view, and in applying measure-based filtrations for persistent homology. ...

We propose a definition of persistent Stiefel-Whitney classes of vector bundle filtrations. It relies on seeing vector bundles as subsets of some Euclidean spaces. The usual Čech filtration of such a subset can be endowed with a vector bundle structure, that we call a Čech bundle filtration. We show that this construction is stable and...

We contribute to the theory of topological inference, based on the theory of persistent homology, by proposing three families of filtrations.For each of them, we prove consistency results---that is, the quality of approximation of an underlying geometric object---, and stability results---that is, robustness against initial measurement...

Despite strong stability properties, the persistent homology of filtrations classically used in Topological Data Analysis, such as, e.g. the Cech or Vietoris-Rips filtrations, are very sensitive to the presence of outliers in the data from which they are computed. In this paper, we introduce and study a new family of filtrations, the...
