Contactless heart rate and heart rate variability estimation from neck videos
2025 47th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC)Video-based pulse extraction is a non-contact technique for estimating physiological signals from video recordings. While traditional approaches focus on facial regions due to their high vascularity and accessibility, this study explored the feasibility of extracting pulse signals from neck region, an area less studied in the literature. Nech and chest

Allometric estimation of metabolic rate from heart rate in penguins
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2005Studies of the relationship between heart rate (f(H)) and rate of oxygen consumption (V(.) (O(2))), which are then used to predict field metabolic rate, frequently fail to incorporate body mass as a predictive variable. This is a potentially important omission in the study of animals whose body mass fluctuates substantially during their annual cycle ...

Research Quarterly. American Association for Health, Physical Education and Recreation, 1972
Abstract The ability of adult men accurately to count their postexercise heart rate in the course of actual training was determined, and postexercise heart rate estimation with values determined during running were compared. Subjects were 37 men (30–45 years of age), who practiced the palpation technique of counting the carotid or apical pulse prior to

Estimation of maximal heart rate in recreational football: a field study
European Journal of Applied Physiology, 2020To examine the accuracy of practical indirect methods (i.e., recreational football match and estimation equations) in assessing individual maximal heart rate (HRmax) in recreational football players. Sixty-two untrained male participants engaged in a recreational football intervention (age 39.3 ± 5.8 years, VO2max 41.2 ± 6.2 ml·kg-1·min-1, body mass 81.

Seismocardiography: Toward heart rate variability (HRV) estimation
2015 IEEE International Symposium on Medical Measurements and Applications (MeMeA) Proceedings, 2015Heart rate variability (HRV), the variation in the beat-to-beat heart rate, is a key indicator of the cardiovascular condition of an individual. The purpose of this study was to cross-validate the beat-by-beat time variations in seismocardiography (SCG) with electrocardiography (ECG) for determining ultra-short term HRV indices.

ECG on the Road: Robust and Unobtrusive Estimation of Heart Rate
IEEE Transactions on Biomedical Engineering, 2011Modern automobiles include an increasing number of assistance systems to increase the driver's safety. This feasibility study investigated unobtrusive capacitive ECG measurements in an automotive environment. Electrodes integrated into the driving seat allowed to measure a reliable ECG in 86% of the drivers; when only (light) cotton clothing was worn ...

Cepstral based heart rate estimation
12th Symposium on Neural Network Applications in Electrical Engineering (NEUREL), 2014Heart rate (HR) estimation is of crucial importance in human health evaluation and can be considered as valuable indicator of cardiovascular state. In this paper contact based system for heart rate is presented, where system for HR acquisition is consisted of a laptop and web camera.

Stimulus Characteristics Influencing Estimation of Heart Rate
Psychophysiology, 1981ABSTRACTTwo experiments examined the degree to which external stimulus factors and actual HR influence judgments of HR, general accuracy of estimated HR, and self‐perceptions of accuracy. Both studies employed a heartbeat tracking technique while subjects viewed a series of slides (Experiment 1) or were engaged in various tasks (Experiment 2).

Estimation of breathing rate and heart rate from photoplethysmogram
2017 6th International Conference on Electrical Engineering and Informatics (ICEEI), 2017Photoplethysmograph (PPG) is a simple and cost effective method to assess cardiovascular related parameters such as heart rate, arterial blood oxygen saturation and blood pressure. PPG signal consists of not only synchronized heart beats, but also the rhythms of respiration.
