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
