Methods for physiological status detection

Heart Rate1

1. Traditional HR measurements

• Reliance on contact-based systems (ECG) leads to inconvenience and discomfort.
  • Sensors utilizing contact-based photoplethysmography (cPPG)

This recent advancement enables remote HR estimation from face videos and permits HR estimation from the skin, specifically referring to the facial region.

2.1 Drawback

• A significant portion of these methods concentrate on strictly controlled scenarios, while the generalization capability toward less constrained environments remains uncertain.
• The lack of large-scale HR databases is a
