Analysis of differences between contact and non-contact estimation of blood pressure

Current Directions in Biomedical Engineering
Blood pressure (BP) is a key indicator for cardiac diseases. Although many current works focus on estimating BP using photoplethysmography (PPG), the number of works using imaging PPG, i.e.
