WebWe present a novel approach to category-level 6D object pose and size estimation. To tackle intra-class shape variations, we learn canonical shape space (CASS), a unified representation for a large variety of instances of a certain object category. In particular, CASS is modeled as the latent space of a deep generative model of canonical 3D …

In order to have a well-defined real distribution function for the quantum phase space, which can be a solution for variational action minimizing problems, we reconstruct quantum Mather measures by means of inverse Radon … Webtransformations to the space with coordinates (u,u x,f). As a shorthand, we denote v := u x and ˜v := ˜u x˜ = V(u,v) := C−1 1 ϕ ′(u)v. In other words, we will in fact study diﬀerential invariants of the projection G1 of G∼ to the space with coordinates (u,v,f), where u and v are the independent variables and f is the dependent variable.
