In this paper we propose a new family of metrics on the manifold of oriented ellipses centered at the origin in Euclidean n-space, the double cover of the manifold of positive semi-definite matrices of rank two, in order to measure similarities betwe

We analyze human poses and motion by introducing three sequences of easily calculated surface descriptors that are invariant under reparametrizations and Euclidean transformations. These descriptors are obtained by associating to each finitely-triang

The proofs and applications are based on a Riemannian version of Gromov’s non-squeezing theorem and classical integral geometry. Given a convex surface Σ ⊂ R and a point q in the unit sphere S we denote by UΣ(q) the perimeter of the orthogonal
