Abstract: In this letter, we address the 3D link segmentation problem of articulated objects using multiple point sets with different configurations. We are motivated by the fact that a point set of an object can be… read more here.

DOI: 10.1109/tvcg.2023.3239370
Abstract: Embedding unified skeletons into unregistered scans is fundamental to finding correspondences, depicting motions, and capturing underlying structures among the articulated objects in the same category. Some existing approaches rely on laborious registration to adapt a… read more here.

DOI: 10.1126/scirobotics.aaw4523
Abstract: A “pull” message passing algorithm is an efficient nonparametric belief propagation for pose estimation of articulated objects. Robots working in human environments often encounter a wide range of articulated objects, such as tools, cabinets, and… read more here.
