A Multi-Channel Ratio-of-Ratios Method for Noncontact Hand Video Based SpO Monitoring Using Smartphone Cameras
Xin Tian, Chau-Wai Wong, Sushant M. Ranadive +1
Blood oxygen saturation (SpO) is an important indicator for pulmonary and respiratory functionalities. Clinical findings on COVID-19 show that many patients had dangerously low…
Remote Blood Oxygen Estimation From Videos Using Neural Networks
Joshua Mathew, Xin Tian, Min Wu +1
Blood oxygen saturation (SpO) is an essential indicator of respiratory functionality and is receiving increasing attention during the COVID-19 pandemic. Clinical findings show…
Cross-domain Joint Dictionary Learning for ECG Inference from PPG
Xin Tian, Qiang Zhu, Yuenan Li +1
The inverse problem of inferring electrocardiogram (ECG) from photoplethysmogram (PPG) is an emerging research direction that combines the easy measurability of PPG and the rich cl…
Inferring ECG from PPG for Continuous Cardiac Monitoring Using Lightweight Neural Network
Yuenan Li, Xin Tian, Qiang Zhu +1
This paper presents a computational solution that enables continuous cardiac monitoring through cross-modality inference of electrocardiogram (ECG). While some smartwatches now all…
Transparency Tools for Fairness in AI (Luskin)
Mingliang Chen, Aria Shahverdi, Sarah Anderson +5
We propose new tools for policy-makers to use when assessing and correcting fairness and bias in AI algorithms. The three tools are: - A new definition of fairness called "controll…
Towards Threshold Invariant Fair Classification
Mingliang Chen, Min Wu
Effective machine learning models can automatically learn useful information from a large quantity of data and provide decisions in a high accuracy. These models may, however, lead…
Adaptive Multi-Trace Carving for Robust Frequency Tracking in Forensic Applications
Qiang Zhu, Mingliang Chen, Chau-Wai Wong +1
In the field of information forensics, many emerging problems involve a critical step that estimates and tracks weak frequency components in noisy signals. It is often challenging…
Respiratory Rate Estimation from Face Videos
Mingliang Chen, Qiang Zhu, Harrison Zhang +2
Vital signs, such as heart rate (HR), heart rate variability (HRV), respiratory rate (RR), are important indicators for a person's health. Vital signs are traditionally measured wi…
ECG Reconstruction via PPG: A Pilot Study
Qiang Zhu, Xin Tian, Chau-Wai Wong +1
In this paper, the relation between electrocardiogram (ECG) and photoplethysmogram (PPG) signals is studied, and the waveform of ECG is inferred via the PPG signals. In order to ad…
