SRH-Net: Stacked Recurrent Hourglass Network for Stereo Matching

1 code implementation25 May 2021 Hongzhi Du, Yanyan Li, Yanbiao Sun, Jigui Zhu, Federico Tombari

The cost aggregation strategy shows a crucial role in learning-based stereo matching tasks, where 3D convolutional filters obtain state of the art but require intensive computation resources, while 2D operations need less GPU memory but are sensitive to domain shift.

A Liouville theorem for Möbius invariant equations

no code implementations31 Dec 2020 Yanyan Li, Han Lu, Siyuan Lu

In this paper we classify M\"{o}bius invariant differential operators of second order in two dimensional Euclidean space, and establish a Liouville type theorem for general M\"{o}bius invariant elliptic equations.

RGB-D SLAM with Structural Regularities

1 code implementation15 Oct 2020 Yanyan Li, Raza Yunus, Nikolas Brasch, Nassir Navab, Federico Tombari

This work proposes a RGB-D SLAM system specifically designed for structured environments and aimed at improved tracking and mapping accuracy by relying on geometric features that are extracted from the surrounding.


Structure-SLAM: Low-Drift Monocular SLAM in Indoor Environments

1 code implementation5 Aug 2020 Yanyan Li, Nikolas Brasch, Yida Wang, Nassir Navab, Federico Tombari

In this paper a low-drift monocular SLAM method is proposed targeting indoor scenarios, where monocular SLAM often fails due to the lack of textured surfaces.


Existence and uniqueness of Green's functions to nonlinear Yamabe problems

no code implementations3 Jan 2020 Yanyan Li, Luc Nguyen

For a given finite subset $S$ of a compact Riemannian manifold $(M, g)$ whose Schouten curvature tensor belongs to a given cone, we establish a necessary and sufficient condition for the existence and uniqueness of a conformal metric on $M \setminus S$ such that each point of $S$ corresponds to an asymptotically flat end and that the Schouten tensor of the conformal metric belongs to the boundary of the given cone.
