The Science Behind Contactless Health Monitoring

  • Facial Detection & Tracking — Multi-face tracking with 68-point landmark detection
  • Region of Interest (ROI) Isolation — Focus on forehead, cheeks, nose for optimal signal
  • Photoplethysmography (PPG) Signal Extraction — Detect subtle color changes from blood flow
  • Noise Reduction & Filtering — Remove motion artifacts, lighting variations
  • Vital Sign Calculation — FFT analysis, peak detection, waveform analysis
  • Machine Learning Enhancement — Neural networks improve accuracy over time

What Makes It Unique:

  • Multi-vital simultaneous extraction — Not just heart rate
  • Works during natural conversation — No need to stay still
  • Adapts to skin tones — Validated across diverse populations
  • Low bandwidth optimized — Works on 3G connections
  • Offline-capable — Basic processing on-device
