Influences on rPPG-Based Spatial Blood Perfusion Maps
Current Directions in Biomedical EngineeringRecent studies show the feasibility of using local remote photoplethysmography (rPPG) for non-contact blood perfusion assessment by creating spatial pulsatile blood perfusion maps. While global rPPG has been widely studied for its robustness, e.g.

Monitoring of Tissue Perfusion During Arterial Occlusion With Remote Photoplethysmographic Imaging. [PDF]
J BiophotonicsThis study evaluated remote photoplethysmography for tracking perfusion during arterial occlusion while assessing cuff pressure and placement. Similar local responses were observed across pressures and locations, supporting rPPG as a perfusion‐monitoring tool and establishing 150 mmHg lower‐arm occlusion as a standardized protocol.

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

Performance Evaluation of rPPG Approaches with and without the Region-of-Interest Localization Step
Applied Sciences, 2021 Traditionally, the first step in physiological measurements based on remote photoplethysmography (rPPG) is localizing the region of interest (ROI) that contains a desired pulsatile information. Recently, approaches that do not require this step have been
