Learning Multimodal Sensor Fusion with JEPA Representations for Breathing Activity and Pose Recognition
Yunxiang Luo, Constantino Álvarez Casado, Xiaoting Wu +4
Predictive video representations do not by themselves specify how a multimodal system should handle missing sensors. We transfer frozen V-JEPA2 features to a set of heterogeneous s…
Oracle headroom without signal: null-calibrated evaluation of candidate selection for thermal heart rate estimation
Mohammad Rakibur Rahman, Nhi Nguyen, Sasan Sharifipour +4
Camera-based physiological monitoring can produce multiple estimates from several facial regions, extraction methods, and processing settings. Signal quality indices aim to select…
Phenomenon-Graph JEPA: Label-Efficient Representation Learning for Contactless Cardiorespiratory Sensing
Constantino Álvarez Casado, Nhi Nguyen, Mohammad Rakibur Rahman +4
Millimeter-wave (mmWave) radar and RGB-D cameras can record cardiac and respiratory waveforms continuously and without contact, but labeled recordings remain scarce because every l…
Handwritten Digit Leakage from Smartphone Motion Sensors Across Unseen Users and Phone Models
Constantino Álvarez Casado, Erkka Rantahalvari, Matteo Pedone +6
Smartphone motion sensors support interactive applications, but their readings may also reveal touchscreen input beyond their intended use. Assuming known drawing intervals, we stu…
Quality-Aware Framework for Video-Derived Respiratory Signals
Nhi Nguyen, Constantino Álvarez Casado, Le Nguyen +2
Video-based respiratory rate (RR) estimation is often unreliable due to inconsistent signal quality across extraction methods. We present a predictive, quality-aware framework that…
LiDAR-based Human Activity Recognition through Laplacian Spectral Analysis
Sasan Sharifipour, Constantino Álvarez Casado, Le Nguyen +4
Human Activity Recognition supports applications in healthcare, manufacturing, and human-machine interaction. LiDAR point clouds offer a privacy-preserving alternative to cameras a…
OMuSense-23: A Multimodal Dataset for Contactless Breathing Pattern Recognition and Biometric Analysis
Manuel Lage Cañellas, Le Nguyen, Anirban Mukherjee +6
In the domain of non-contact biometrics and human activity recognition, the lack of a versatile, multimodal dataset poses a significant bottleneck. To address this, we introduce th…
Evaluation of Video-Based rPPG in Challenging Environments: Artifact Mitigation and Network Resilience
Nhi Nguyen, Le Nguyen, Honghan Li +2
Video-based remote photoplethysmography (rPPG) has emerged as a promising technology for non-contact vital sign monitoring, especially under controlled conditions. However, the acc…
Multi-objective Feature Selection in Remote Health Monitoring Applications
Le Ngu Nguyen, Constantino Álvarez Casado, Manuel Lage Cañellas +4
Radio frequency (RF) signals have facilitated the development of non-contact human monitoring tasks, such as vital signs measurement, activity recognition, and user identification.…
Non-contact Multimodal Indoor Human Monitoring Systems: A Survey
Le Ngu Nguyen, Praneeth Susarla, Anirban Mukherjee +6
Indoor human monitoring systems leverage a wide range of sensors, including cameras, radio devices, and inertial measurement units, to collect extensive data from users and the env…
Estimating exercise-induced fatigue from thermal facial images
Manuel Lage Cañellas, Constantino Álvarez Casado, Le Nguyen +1
Exercise-induced fatigue resulting from physical activity can be an early indicator of overtraining, illness, or other health issues. In this article, we present an automated metho…
Respiratory Disease Classification and Biometric Analysis Using Biosignals from Digital Stethoscopes
Constantino Álvarez Casado, Manuel Lage Cañellas, Matteo Pedone +3
Respiratory diseases remain a leading cause of mortality worldwide, highlighting the need for faster and more accurate diagnostic tools. This work presents a novel approach leverag…
Non-Contact Heart Rate Measurement from Deteriorated Videos
Nhi Nguyen, Le Nguyen, Constantino Álvarez Casado +2
Remote photoplethysmography (rPPG) offers a state-of-the-art, non-contact methodology for estimating human pulse by analyzing facial videos. Despite its potential, rPPG methods can…
