Micro-DualNet: Dual-Path Spatio-Temporal Network for Micro-Action Recognition
Naga VS Raviteja Chappa, Evangelos Sariyanidi, Lisa Yankowitz +4
Micro-actions are subtle, localized movements lasting 1-3 seconds such as scratching one's head or tapping fingers. Such subtle actions are essential for social communication, ubiq…
EventGeM: Global-to-Local Feature Matching for Event-Based Visual Place Recognition
Adam D. Hines, Gokul B. Nair, Nicolás Marticorena +2
Event cameras are rapidly rising in popularity for robotic and computer vision tasks because their sparse activation delivers energy-efficient, high-dynamic-range, and fast sensing…
Event-Based Visual Teach-and-Repeat via Fast Fourier-Domain Cross-Correlation
Gokul B. Nair, Alejandro Fontan, Michael Milford +1
Visual teach-and-repeat (VT&R) navigation enables robots to autonomously traverse previously demonstrated paths using visual feedback. We present a novel event-camera-based VT&R sy…
Enhancing Visual Place Recognition via Fast and Slow Adaptive Biasing in Event Cameras
Gokul B. Nair, Michael Milford, Tobias Fischer
Event cameras are increasingly popular in robotics due to beneficial features such as low latency, energy efficiency, and high dynamic range. Nevertheless, their downstream task pe…
BirdSLAM: Monocular Multibody SLAM in Bird's-Eye View
Swapnil Daga, Gokul B. Nair, Anirudha Ramesh +3
In this paper, we present BirdSLAM, a novel simultaneous localization and mapping (SLAM) system for the challenging scenario of autonomous driving platforms equipped with only a mo…
Multi-object Monocular SLAM for Dynamic Environments
Gokul B. Nair, Swapnil Daga, Rahul Sajnani +4
In this paper, we tackle the problem of multibody SLAM from a monocular camera. The term multibody, implies that we track the motion of the camera, as well as that of other dynamic…
