  1. OMNIVIEWS DEMOS • SURVEILLANCE DEMOS • TRANSMISSION DEMO • NAVIGATION DEMOS

  2. Visual Tracking with Omnidirectional Sensors • The algorithm: • Minimize the SSD. • Test hypothesis of main translational motion. • Consider other small deformations (e.g. rotation, scale) to cope with deviations from model. • Applications: • Robot navigation: track landmarks. Robot heading is directly related to target image position. • Video Conferencing/Surveillance: keep attention focus on people/faces. Alexandre Bernardino, José Santos-Victor Instituto Superior Técnico
