Population

36 challenging benchmark videos consisting of subjects that differ in gender, skin types, and performed motion categories

Intervention

Novel rPPG framework using motion-compensated pixel-to-pixel pulse extraction, spatial pruning, and temporal filtering

Comparator

State-of-the-art rPPG technique

Outcome

Signal-to-noise ratio (SNR) and agreement (±1.96σ) with instantaneous reference pulse ratesurrogate

A novel rPPG framework exploiting spatial redundancy significantly improves motion robustness, achieving performance close to contact-based sensors.

Limitations

Not based on a full clinical trial
