Hearables: In-Ear Multimodal Data Fusion for Robust Heart Rate Estimation

BioMedInformatics
Background: Ambulatory heart rate (HR) monitors that acquire electrocardiogram (ECG) or/and photoplethysmographm (PPG) signals from the torso, wrists, or ears are notably less accurate in tasks associated with high levels of movement compared to clinical

Validity and Reliability of the Heart Rate Matching Task: A Novel Measure of Heart Rate Estimation. [PDF]

Psychophysiology
ABSTRACT Sensing and monitoring changes in our heart rate is a key aspect of interoception. We introduce and test the construct validity of the Heart Rate Matching task (HRM), a novel, fast and accessible task designed to assess the ability to estimate heart rate, in both remote (i.e., online) and in‐lab settings.

RealSense = real heart rate: Illumination invariant heart rate estimation from videos [PDF]

2016 Sixth International Conference on Image Processing Theory, Tools and Applications (IPTA), 2016
Recent studies validated the feasibility of estimating heart rate from human faces in RGB video. However, test subjects are often recorded under controlled conditions, as illumination variations significantly affect the RGB-based heart rate estimation accuracy.

Heart rate estimation in intense exercise videos

2022 IEEE International Conference on Image Processing (ICIP), 2022
Estimating heart rate from video allows non-contact health monitoring with applications in patient care, human interaction, and sports. Existing work can robustly measure heart rate under some degree of motion by face tracking.

HBP-net for robust remote heart rate estimation using heartbeat probability [PDF]

iScience
Summary: Remote photoplethysmography (rPPG) enables contactless heart rate monitoring but remains vulnerable to motion and lighting changes. We address this by reframing heart rate estimation as a heartbeat detection problem, bypassing the need to ...

Adaptive Beat-to-Beat Heart Rate Estimation in Ballistocardiograms [PDF]

IEEE Transactions on Information Technology in Biomedicine, 2011
A ballistocardiograph records the mechanical activity of the heart. We present a novel algorithm for the detection of individual heart beats and beat-to-beat interval lengths in ballistocardiograms (BCGs) from healthy subjects. An automatic training step based on unsupervised learning techniques is used to extract the shape of a single heart beat from ...
