SAM3 Expertise Areas: Video Analysis

Video provides a rich source of data and through analysis that can lead to knowledge about well-being. Video is applied carefully given the privacy intrusion that it represents. SAM3 researchers have used video analysis for a number of applications.

Video applications

  • Gait and other motion assessment
  • Kitchen use and kitchen safety
  • Driving assessment
  • Driver gaze assessment
  • Cognitive assessment
  • Thermal and RGB camera based assessment
