FairReL: Deepfake Detection using Fairness-Aware Representation Learning
Xiaoman Lu, Jiaqi Li, Shuntian Zheng +2
Although recent deepfake detectors achieve high overall accuracy, their errors remain unevenly distributed across demographic subgroups, with real faces from certain groups more of…
Physics-Bounded mmWave Sensing for Schedulable, Privacy-Preserving Human Pose Estimation
Shuntian Zheng, Hongyang He, Jiaqi Li +6
Millimeter-wave (mmWave) is a promising modality for human pose estimation (HPE) in mobile deployments with strong privacy requirements and limited resources, such as fall detectio…
Rethinking PPG-based Sleep Staging: Datasets, Metrics, and Benchmarks
Shuntian Zheng, Jiawei Wang, Cong Fu +4
Automated sleep staging assigns discrete stage labels to successive time epochs throughout an overnight recording; conventionally each window spans at least 30 seconds, reflecting…
Doppler Prompting for Stable mmWave-based Human Pose Estimation
Shuntian Zheng, Jiaqi Li, Xiaoman Lu +2
Millimeter-wave (mmWave) enables privacy-preserving, illumination-robust human pose estimation (HPE), with each mmWave frame represented as a range-angle-Doppler tensor, providing…
A Two-Stage Motion-Aware Framework for mmWave-based Human Mesh Recovery
Hoang Hai Pham, Shuntian Zheng, Jiaqi Li +1
Millimeter-wave (mmWave) radar has emerged as a promising sensing modality for human perception due to its robustness under challenging environmental conditions and strong privacy-…
Why Learn What Physics Already Knows? Realizing Agile mmWave-based Human Pose Estimation via Physics-Guided Preprocessing
Shuntian Zheng, Jiaqi Li, Minzhe Ni +2
We revisit millimeter-wave (mmWave) human pose estimation (HPE) from a signal preprocessing perspective. A single mmWave frame provides structured dimensions that map directly to h…
