Journal Article
Avila Castro, I. A., Oliveira, H., Goncalves Correia, R., Hayes-Gill, B. R., Morgan, S. P., Korposh, S., Gomez, D., & Pereira, T. (2025). Generative adversarial networks with fully connected layers to denoise PPG signals. Physiological Measurement, 46(2), Article 025008. https://doi.org/10.1088/1361-6579/ada9c1

Objective.The detection of arterial pulsating signals at the skin periphery with Photoplethysmography (PPG) are easily distorted by motion artifacts. This work explores the alternatives to the aid of PPG reconstruction with movement sensors (accelero...
