Expertise: Video Magnification
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
