Vascular ageing is the deterioration of arterial structure and function which occurs naturally with age, and which can be accelerated with disease. Measurements of vascular ageing are emerging as markers of cardiovascular risk, with potential applications in disease diagnosis and prognosis, and for guiding treatments. However, vascular ageing is no...
Pulse rate (PR) is one of the most important markers for assessing a person's health. With the increasing demand for long-term health monitoring, much attention is being paid to contactless PR estimation using imaging photoplethysmography (iPPG). This non-invasive technique is based on the analysis of subtle changes in skin color. Despite efforts t...
La mesure de signaux photopléthysmographiques (PPG) sans contact est une technique de mesure non invasive permettant d'estimer un ensemble de fonctions vitales par analyse vidéo délivrée par caméra. Nous proposons, dans cet article, une méthode permettant de convertir un signal PPG mesuré par caméra en un signal PPG mesuré en contact (cPPG). L'obje...
Background
The remote measurement of physiological signals from video has gained a particular attention over the last past years. Estimating cardiovascular parameters like oxygen saturation and arterial blood pressure (BP) is covered by a limited volume of studies and remain a very challenging issue. Recent attempts demonstrated that BP can be esti...
Human's affective state recognition remains a challenging topic due to the complexity of emotions, which involves experiential, behavioral, and physiological elements. Since it is difficult to comprehensively describe emotion in terms of single modalities, recent studies have focused on fusion strategy to exploit the complementarity of multimodal s...
Les pathologies cardiovasculaires sont désignées par l'OMS comme étant la première cause de mortalité dans le monde. Elles sont responsables de près de la moitié des maladies invalidantes aujourd'hui. Un ensemble de technologies per-mettent de mesurer différents signaux physiologiques et fonctions vitales sans qu'aucun contact avec la personne ne s...
We present in this paper the LCOMS Lab's approach to the 1st Vision For Vitals (V4V) Challenge organized within ICCV2021. The V4V challenge was focused on computer vision methods for vitals signs measurement from facial videos, including pulse rate (PR) and respiratory rate. We propose a novel end-to-end architecture based on a deep spatiotemporal...
Imaging photoplethysmography (iPPG) is an optical technique dedicated to the assessment of several vital functions using a simple camera. Significant efforts have been made to reliably estimate heart and respiratory rates. Currently, research is focusing on the remote estimation of oxygen saturation and blood pressure (BP). The limited number of pu...
Recent technological advances in the field of sensors, signal processing and image processing favor the development of new techniques for vital parameters monitoring such as imaging photoplethysmography (iPPG). iPPG is a simple and noninvasive measurement technique. It has been employed to remotely estimate heart and respiratory rates, oxygen satur...
Désignées par l'OMS comme étant la première cause de mortalité dans le monde, les pathologies respiratoires ou car-diovasculaires sont responsables de près de la moitié des maladies invalidantes. Différentes technologies permettent désormais de mesurer signaux physiologiques et fonctions vitales sans qu'aucun contact avec la personne ne soit nécess...
