Blood oxygen saturation (SpO$_2$) is an essential indicator of respiratory
functionality and is receiving increasing attention during the COVID-19
pandemic. Clinical findings show that it is possible for COVID-19 patients to
have significantly low SpO$_2$ before any obvious symptoms. The prevalence of
cameras has motivated researchers to investigate methods for monitoring SpO$_2$
using videos. Most prior schemes involving smartphones are contact-based: They
require a fingertip to cover the phone's camera and the nearby light source to
capture re-emitted light from …
