A Linear Comb Filter for Event Flicker Removal
Ziwei Wang, Dingran Yuan, Yonhon Ng +1
Event cameras are bio-inspired sensors that capture per-pixel asynchronous intensity change rather than the synchronous absolute intensity frames captured by a classical camera sen…
Uncertainty Estimation of Dense Optical-Flow for Robust Visual Navigation
Yonhon Ng, Hongdong Li, Jonghyuk Kim
This paper presents a novel dense optical-flow algorithm to solve the monocular simultaneous localization and mapping (SLAM) problem for ground or aerial robots. Dense optical flow…
Equivariant Systems Theory and Observer Design for Second Order Kinematic Systems on Matrix Lie Groups
Yonhon Ng, Pieter van Goor, Tarek Hamel +1
This paper presents the equivariant systems theory and observer design for second order kinematic systems on matrix Lie groups. The state of a second order kinematic system on a ma…
Attitude Observation for Second Order Attitude Kinematics
Yonhon Ng, Pieter van Goor, Robert Mahony +1
This paper addresses the problem of estimating the attitude and angular velocity of a rigid object by exploiting its second order kinematic model. The approach is particularly usef…
Event Camera Calibration of Per-pixel Biased Contrast Threshold
Ziwei Wang, Yonhon Ng, Pieter van Goor +1
Event cameras output asynchronous events to represent intensity changes with a high temporal resolution, even under extreme lighting conditions. Currently, most of the existing wor…
