Towards passive heart health monitoring via smartphone camera
AI summary
Google Research published a study in Nature introducing PHRM, which records video with a phone’s front camera in the seconds after face unlock and uses deep learning to estimate heart rate and resting heart rate in the background.

- Why it was chosen
- Passive heart-rate measurement after face unlock, alongside the largest phone-video dataset and pretrained model released to date, shows the real-world limits of rPPG.
A model scores each item twice, independently, against one written standard, out of 100. An item is admitted only when the two scores add up to twice the threshold. The threshold is set per source tier.
