Motion Segmentation for Neuromorphic Aerial Surveillance

Motion Segmentation for Neuromorphic Aerial Surveillance

This paper addresses these challenges by introducing a novel motion segmentation method that leverages self-supervised vision transformers on both event data and optical flow information. Our approach eliminates the need for human annotations and reduces dependency on scene-specific parameters.

CoSEC: A Coaxial Stereo Event Camera Dataset for Autonomous Driving

This paper introduces hybrid coaxial event-frame devices to build the multimodal system, and propose a coaxial stereo event camera (CoSEC) dataset for autonomous driving. As for the multimodal system, it first utilizes the microcontroller to achieve time synchronization, and then spatially calibrate different sensors, where they perform intra- and inter-calibration of stereo coaxial devices.

Asynchronous Optimisation for Event-based Visual Odometry

Asynchronous Optimisation for Event-based Visual Odometry

This paper focuses on event-based visual odometry (VO). While existing event-driven VO pipelines have adopted continuous-time representations to asynchronously process event data, they either assume a known map, restrict the camera to planar trajectories, or integrate other sensors into the system. Towards map-free event-only monocular VO in SE(3), we propose an asynchronous structure-from-motion optimisation back-end.

Target-free Extrinsic Calibration of Event-LiDAR Dyad using Edge Correspondences

Target-free Extrinsic Calibration of Event-LiDAR Dyad using Edge Correspondences

This paper proposes a novel method to calibrate the extrinsic parameters between a dyad of an event camera and a LiDAR without the need for a calibration board or other equipment. Our approach takes advantage of the fact that when an event camera is in motion, changes in reflectivity and geometric edges in the environment trigger numerous events, which can also be captured by LiDAR.

eTraM: Event-based Traffic Monitoring Dataset

Event cameras offer high temporal resolution and efficiency but remain underutilized in static traffic monitoring. We present eTraM, a first-of-its-kind event-based dataset with 10 hours of traffic data, 2M annotations, and eight participant classes. Evaluated with RVT, RED, and YOLOv8, eTraM highlights the potential of event cameras for real-world applications.

Heart Rate Detection Using an Event Camera

This paper proposes to harness the surface of the skin caused by the pulsatile flow of blood in the wrist region. It investigates whether an event camera could be used for continuous noninvasive monitoring of heart rate (HR). Event camera video data from 25 participants, comprising varying age groups and skin colours, was collected and analysed.
