Non-Contrastive Unsupervised Learning of Physiological Signals from Video

open access: yes, 2023
Subtle periodic signals such as blood volume pulse and respiration can be extracted from RGB video, enabling remote health monitoring at low cost. Advancements in remote pulse estimation -- or remote photoplethysmography (rPPG) -- are currently driven by
