SleepBand: Single-Source Domain Generalization for Sleep Staging via Physiologically Structured Spectral Modeling
Zhi Lu, Yang Hu, Yan Chen
Generalizing sleep staging models to unseen datasets is challenging, and typical domain generalization (DG) methods often rely on multiple source domains or domain labels that are…
rPPG-VQA: A Video Quality Assessment Framework for Unsupervised rPPG Training
Tianyang Dai, Ming Chang, Yan Chen +1
Unsupervised remote photoplethysmography (rPPG) promises to leverage unlabeled video data, but its potential is hindered by a critical challenge: training on low-quality "in-the-wi…
Automatic Phase Calibration for High-resolution mmWave Sensing via Ambient Radio Anchors
Ruixu Geng, Yadong Li, Dongheng Zhang +6
Millimeter-wave (mmWave) radar systems with large array have pushed radar sensing into a new era, thanks to their high angular resolution. However, our long-term experiments indica…
Passive Non-Line-of-Sight Imaging with Light Transport Modulation
Jiarui Zhang, Ruixu Geng, Xiaolong Du +3
Passive non-line-of-sight (NLOS) imaging has witnessed rapid development in recent years, due to its ability to image objects that are out of sight. The light transport condition p…
A Survey of Wireless Sensing Security from a Role-Based View: Victim, Weapon, and Shield
Ruixu Geng, Jianyang Wang, Yuqin Yuan +8
Wireless sensing technology has become prevalent in healthcare, smart homes, and autonomous driving due to its non-contact operation, penetration capabilities, and cost-effectivene…
