May aid remote heart rate monitoring in low light; hypothesis-generating and requires clinical validation before adoption.
Lin et al. (2020) studied Remote heart rate estimation. Low-light enhancement solution for rPPG vs. Standard rPPG algorithms (Green, ICA, POS) was evaluated on Signal-to-noise ratio and precision of the pulsatile signal. A proposed low-light enhancement solution for remote photoplethysmography effectively improved the signal-to-noise ratio and precision of pulsatile signals in dark environments.
