SAM3 Expertise Areas: Video Magnification

Video Magnification is a technique to identify small changes in video that are invisible to the naked eye but can be identified with advanced signal processing. This technique can provide a method for the assessment of well-being and specifically remote assessment of vitals signs. SAM3 researchers have extensive publications related to video magnification.

Video Magnification Application Areas

  • Heart rate, Pulse Transit Time and relative blood pressure assessment
  • Respiration rate assessment
  • Applications using thermal and RGB video
  • Applications using colour and/or motion magnification
