Semi-rPPG: Semi-Supervised Remote Physiological Measurement With Curriculum Pseudo-Labeling
IEEE Transactions on Instrumentation and MeasurementRemote Photoplethysmography (rPPG) is a promising technique to monitor physiological signals such as heart rate from facial videos. However, the labeled facial videos in this research are challenging to collect. Current rPPG research is mainly based on several small public datasets collected in simple environments, which limits the generalization and ...

rPPG-MAE: Self-Supervised Pretraining With Masked Autoencoders for Remote Physiological Measurements
IEEE Transactions on MultimediaRemote photoplethysmography (rPPG) is an important technique for perceiving human vital signs, which has received extensive attention. For a long time, researchers have focused on supervised methods that rely on large amounts of labeled data. These methods are limited by the requirement for large amounts of data and the difficulty of acquiring ground ...

Enhancing rPPG pulse-signal recovery by facial sampling and PSD Clustering
Biomedical Signal Processing and ControlIn order to increase the accuracy of traditional methods for camera-based pulse rate estimation, we propose a novel systemic approach that extracts multiple remote photoplethysmography (rPPG) signals from a set of scattered facial patches and effectively separates good estimates from noisy ones via a novel unsupervised Power Spectral Density (PSD ...

Periodic-MAE: Periodic Video Masked Autoencoder for rPPG Estimation
In this paper, we propose a method that learns a general representation of periodic signals from unlabeled facial videos by capturing subtle changes in skin tone over time. The proposed framework employs the video masked autoencoder to learn a high-dimensional spatio-temporal representation of the facial region through self-supervised learning ...
