Asynchronous Tracking, Optical Communication and 3D Motion Capture using Event-based Sensors
Ziwei Wang, Angus Apps, Holly Battisson +3
Inter-robot communication is a key enabling technology in cooperative robotics applications. While wireless communication is ubiquitous, simple, and effective, it has inherent limi…
SkillPlug: Unsupervised Skill Mining for Few-Shot Adaptation in Robotic Manipulation
Zi-han Ding, Ziwei Wang
Learning transferable visuomotor imitation policies that generalize across diverse manipulation tasks and adapt rapidly to new tasks from only a handful of demonstrations remains c…
Asynchronous Multi-Object Tracking with an Event Camera
Angus Apps, Ziwei Wang, Vladimir Perejogin +2
Events cameras are ideal sensors for enabling robots to detect and track objects in highly dynamic environments due to their low latency output, high temporal resolution, and high…
An Asynchronous Linear Filter Architecture for Hybrid Event-Frame Cameras
Ziwei Wang, Yonhon Ng, Cedric Scheerlinck +1
Event cameras are ideally suited to capture High Dynamic Range (HDR) visual information without blur but provide poor imaging capability for static or slowly varying scenes. Conver…
Asynchronous Blob Tracker for Event Cameras
Ziwei Wang, Timothy Molloy, Pieter van Goor +1
Event-based cameras are popular for tracking fast-moving objects due to their high temporal resolution, low latency, and high dynamic range. In this paper, we propose a novel algor…
Smart Visual Beacons with Asynchronous Optical Communications using Event Cameras
Ziwei Wang, Yonhon Ng, Jack Henderson +1
Event cameras are bio-inspired dynamic vision sensors that respond to changes in image intensity with a high temporal resolution, high dynamic range and low latency. These sensor c…
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…
Stereo Hybrid Event-Frame (SHEF) Cameras for 3D Perception
Ziwei Wang, Liyuan Pan, Yonhon Ng +2
Stereo camera systems play an important role in robotics applications to perceive the 3D world. However, conventional cameras have drawbacks such as low dynamic range, motion blur…
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…
An Asynchronous Kalman Filter for Hybrid Event Cameras
Ziwei Wang, Yonhon Ng, Cedric Scheerlinck +1
Event cameras are ideally suited to capture HDR visual information without blur but perform poorly on static or slowly changing scenes. Conversely, conventional image sensors measu…
