Photoplethysmography upon cold stress-impact of measurement site and acquisition mode.

Photoplethysmography (PPG) allows various statements about the physiological state. It supports multiple recording setups, i.e.

Beat-to-Beat Blood Pressure Estimation by Photoplethysmography and Its Interpretation.

Blood pressure (BP) is among the most important vital signals. Estimation of absolute BP solely using photoplethysmography (PPG) has gained immense attention over the last years. Available works differ in terms of used features as well as classifiers and bear large differences in their results.

Adaptive Gaussian Mixture Model Driven Level Set Segmentation for Remote Pulse Rate Detection.

This paper presents an approach for pulse rate extraction from videos. The core of the presented approach is a novel method to segment and track a suitable region of interest (ROI). The proposed method combines level sets with subject-individual Gaussian Mixture Models to yield a time varying ROI.

Pulse decomposition analysis in photoplethysmography imaging.

Objective: Photoplethysmography imaging (PPGI) has gained immense attention over the last few years but only a few works have addressed morphological analysis so far. Pulse wave decomposition (PWD), i.e.
