Chip-Surface Based Visual Authentication for Integrated Circuits
Runze Liu, Prasun Datta, Anirudh Nakra +2
The rapid development of the semiconductor industry and the ubiquity of electronic devices have led to a significant increase in the counterfeiting of integrated circuits (ICs). Th…
Contact-Free Simultaneous Sensing of Human Heart Rate and Canine Breathing Rate for Animal Assisted Interactions
Timothy Holder, Mushfiqur Rahman, Emily Summers +3
Animal Assisted Interventions (AAIs) involve pleasant interactions between humans and animals and can potentially benefit both types of participants. Research in this field may hel…
Group Testing with Side Information via Generalized Approximate Message Passing
Shu-Jie Cao, Ritesh Goenka, Chau-Wai Wong +2
Group testing can help maintain a widespread testing program using fewer resources amid a pandemic. In a group testing setup, we are given n samples, one per individual. Each indiv…
Mismatched Estimation in the Distance Geometry Problem
Mahmoud Abdelkhalek, Dror Baron, Chau-Wai Wong
We investigate mismatched estimation in the context of the distance geometry problem (DGP). In the DGP, for a set of points, we are given noisy measurements of pairwise distances b…
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…
On Microstructure Estimation Using Flatbed Scanners for Paper Surface Based Authentication
Runze Liu, Chau-Wai Wong
Paper surfaces under the microscopic view are observed to be formed by intertwisted wood fibers. Such structures of paper surfaces are unique from one location to another and are a…
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…
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…
