Dynamic ROI Adaptation for Accurate Non-Contact Heart Rate Estimation Using VGG-13 based Encoder-Decoder Model and Facial Landmarks

ICASSP 2025accepted

Heart rate monitoring using cameras is gaining attention for unobtrusive health tracking. This paper proposes an improved method for HR calculation using ROI adaptation tailored to individual facial features. A VGG-13 based encoder-decoder model was used for skin segmentation, classifying image pixe…

Signaling Endothelial Reactivity Induced by Acute Hand Grip: Analyzing Vessel Diameter, Flow Velocity, and EMG Responses

ICASSP 2025accepted

Conventional occlusion-based flow-mediated dilation (FMD) for assessing endothelial reactivity (ER) faces challenges such as operator and/or subject-dependant variability and time constraints. This study proposes a novel method using acute hand grip (HG) exercise to induce shear stimulus for improve…

Sparse models for determining arterial dynamics

ICASSP 2015accepted

This paper deals with the estimation of the inner-diameter of the Carotid Artery (CA). Arteries pulsate as blood is pumped through them by the heart. Plaque depositions along the inner wall makes the arteries rigid and obstructs the flow of blood. This increases the risk of a heart attack. The dynam…
