NRDF: Neural Riemannian Distance Fields for Learning Articulated Pose Priors

Autor: He, Yannan, Tiwari, Garvita, Birdal, Tolga, Lenssen, Jan Eric, Pons-Moll, Gerard

Faithfully modeling the space of articulations is a crucial task that allows recovery and generation of realistic poses, and remains a notorious challenge. To this end, we introduce Neural Riemannian Distance Fields (NRDFs), data-driven priors modeli

Riemannian distance and symplectic embeddings in cotangent bundle

Autor: Broćić, Filip

Given an open neighborhood $W$ of the zero section in the cotangent bundle of $N$ we define a distance-like function $\rho_W$ on $N$ using certain symplectic embeddings from the standard ball $B^{2n}(r)$ to $W$. We show that when $W$ is the unit disc

Variations of the sub-Riemannian distance on Sasakian manifolds with applications to coupling

Autor: Baudoin, Fabrice, Grong, Erlend, Neel, Robert, Thalmaier, Anton

On Sasakian manifolds with their naturally occurring sub-Riemannian structure, we consider parallel and mirror maps along geodesics of a taming Riemannian metric. We show that these transport maps have well-defined limits outside the sub-Riemannian c
