Remote photoplethysmography (rPPG) to measure heart rate and blood oxygenation levels using colour, infrared and depth data from real home environments

, 2023
Heart Rate (HR) and Blood Oxygenation Level (SPO₂) are physiological signs that are critically important measurements in the assessment of emergent ill-health. These typically require physical contact and blood tests that are often prohibitive for people with certain incapacities, severe illnesses, or burns.
