Robust respiration detection from remote photoplethysmography. [PDF]
Biomed Opt Express, 2016 Continuous monitoring of respiration is essential for early detection of critical illness. Current methods require sensors attached to the body and/or are not robust to subject motion. Alternative camera-based solutions have been presented using motion vectors and remote photoplethysmography.
