An Asynchronous Kalman Filter for Hybrid Event Cameras.
TL;DR: The proposed algorithm includes a frame augmentation pre-processing step that deblurs and temporally interpolates frame data using events and outperforms state-of-the-art methods in both absolute intensity error and image similarity indexes.
Proceedings ArticleDOI
Attitude Observation for Second Order Attitude Kinematics
TL;DR: This paper extends the approach of equivariant observer design to second order attitude kinematics by demonstrating that the special Euclidean group acts as a symmetry group on the system considered and proves almost global asymptotic stability and local uniform exponential stability of the estimation error.
Proceedings ArticleDOI
Equivariant Systems Theory and Observer Design for Second Order Kinematic Systems on Matrix Lie Groups
TL;DR: In this article, an equivariant lift of the kinematics onto the symmetry group is defined and used to design a nonlinear observer on the lifted state space using nonlinear constructive design techniques.

Event Camera Calibration of Per-pixel Biased Contrast Threshold.
TL;DR: A new event camera model and two calibration approaches which cover event-only cameras and hybrid image-event cameras are proposed and an efficient online method to calibrate event cameras that adapts to time-varying event rates is proposed.
Proceedings ArticleDOI
A Linear Comb Filter for Event Flicker Removal
TL;DR: A novel linear filter to preprocess event data to remove unwanted flicker events from an event stream is proposed and achieves over 4.6 times relative improvement in the signal-to-noise ratio when compared to the raw event stream due to the effective removal of flicker from fluorescent lighting.
