Implicitly Defined Layers in Neural Networks

no code implementations3 Mar 2020 Qianggong Zhang, Yanyang Gu, Michalkiewicz Mateusz, Mahsa Baktashmotlagh, Anders Eriksson

In conventional formulations of multilayer feedforward neural networks, the individual layers are customarily defined by explicit functions.

SASSE: Scalable and Adaptable 6-DOF Pose Estimation

no code implementations5 Feb 2019 Huu Le, Tuan Hoang, Qianggong Zhang, Thanh-Toan Do, Anders Eriksson, Michael Milford

In this paper, we present a novel 6-DOF localization system that for the first time simultaneously achieves all the three characteristics: significantly sub-linear storage growth, agnosticism to image descriptors, and customizability to available storage and computational resources.

A Fast Resection-Intersection Method for the Known Rotation Problem

no code implementations CVPR 2018 Qianggong Zhang, Tat-Jun Chin, Huu Minh Le

The known rotation problem refers to a special case of structure-from-motion where the absolute orientations of the cameras are known.

Quasiconvex Plane Sweep for Triangulation With Outliers

no code implementations ICCV 2017 Qianggong Zhang, Tat-Jun Chin, David Suter

Relative to the random sampling heuristic, our algorithm not only guarantees deterministic convergence to a local minimum, it typically achieves higher quality solutions in similar runtimes.

Coresets for Triangulation

no code implementations18 Jul 2017 Qianggong Zhang, Tat-Jun Chin

A coreset possesses the special property that the error of the $\ell_{\infty}$ solution on the coreset is within known bounds from the global minimum.
