EsaacSim: A Multimodal Event Camera Add-on for NVIDIA Isaac Sim
Ignacio Bugueno-Cordova, Malte Kuhlmann, Nicolás Navarro-Guerrero +2
Event-based vision is becoming an increasingly important sensing paradigm for robotics, yet its adoption remains limited by sensor availability and the lack of integrated simulatio…
eBIRD: Event-based Intensity Image Reconstruction Using Controllable Diffusion Models
Ignacio Bugueno-Cordova, Fabian Valderrama, Rodrigo Verschae
Intensity-image reconstruction from event streams remains a challenging problem due to the binary, sparse, and asynchronous nature of event data. This work proposes eBIRD, an event…
PEBRE: An Open-Hardware Compute and Perception Add-On for the Pepper Robot
Malte Kuhlmann, Ignacio Bugueno-Cordova, Emil Alms +2
This paper presents the design, development, and experimental verification of PEBRE, an open-hardware add-on for fast software development on the Pepper Robot. Our project enhances…
Event-based Liveness Detection using Temporal Ocular Dynamics: An Exploratory Approach
Nicolas Mastropasqua, Ignacio Bugueno-Cordova, Rodrigo Verschae +2
Face liveness detection has been extensively studied using RGB cameras, achieving strong performance under controlled conditions but often failing to generalize across sensors and…
evTransFER: A Transfer Learning Framework for Event-based Facial Expression Recognition
Rodrigo Verschae, Ignacio Bugueno-Cordova
Event-based cameras are bio-inspired sensors that asynchronously capture pixel intensity changes with microsecond latency, high temporal resolution, and high dynamic range, providi…
Exploring Spatial-Temporal Dynamics in Event-based Facial Micro-Expression Analysis
Nicolas Mastropasqua, Ignacio Bugueno-Cordova, Rodrigo Verschae +3
Micro-expression analysis has applications in domains such as Human-Robot Interaction and Driver Monitoring Systems. Accurately capturing subtle and fast facial movements remains d…
