AND-rPPG: A novel denoising-rPPG network for improving remote heart rate estimation

Computers in Biology and Medicine, 2022
Heart rate (HR) estimation is an essential physiological parameter in the field of biomedical imaging. Remote Photoplethysmography (r-PPG) is a pathbreaking development in this field wherein the PPG signal is extracted from non-contact face videos. In the COVID-19 pandemic, rPPG plays a vital role for doctors and patients to perform telehealthcare ...

Siamese-rPPG network

Proceedings of the 35th Annual ACM Symposium on Applied Computing, 2020
Remote photoplethysmography (rPPG) is a contactless method for heart rate (HR) estimation from face videos. In this paper, we propose to estimate rPPG signals directly from input video sequences in an end-to-end manner. We propose a novel Siamese-rPPG network to simultaneously learn the heterogeneous and homogeneous features from two facial regions ...

Physiological Imaging using rPPG: Glabrous and Non-glabrous Skin

Latin America Optics and Photonics (LAOP) Conference 2022, 2022
Little is known about differences in the photoplethysmogram (PPG) across glabrous and non-glabrous skin, which is crucial given emerging PPG modalities. Using remote PPG in four subjects, we detected changes in amplitude and temporal lag.

Remote Photoplethysmography (rPPG): A State-of-the-Art Review

2023
Peripheral oxygen saturation (SpO2) and heart rate (HR) are critical physiological measures that clinicians need to observe to decide on an emergency intervention. These measures are typically determined using a contact-based pulse oximeter. This approach may pose difficulties in many cases, such as with young children, patients with burnt or sensitive

Gaze into the Heart: A Multi-View Video Dataset for rPPG and Health Biomarkers Estimation

ACM Multimedia
Progress in remote PhotoPlethysmoGraphy (rPPG) is limited by the critical issues of existing publicly available datasets: small size, privacy concerns with facial videos, and lack of diversity in conditions.
