Remote photoplethysmography with constrained ICA using periodicity and chrominance constraints

BACKGROUND Remote photoplethysmography (rPPG) has been in the forefront recently for measuring cardiac pulse rates from live or recorded videos. It finds advantages in scenarios requiring remote monitoring, such as medicine and fitness, where contact based monitoring is limiting and cumbersome. The blood volume pulse, defined as the pulsative flow of arterial blood, gives rise to periodic chang...

Remote control for videoconferencing

We have designed, implemented, and deployed a camera control system and a conference controller that provide remote control capabilities for videoconferencing over the Internet. The camera control system allows users to pan, tilt, and zoom the cameras, switch between cameras, and get a picture-in-picture view from their desktops. The conference controller allows conference participants to not o...

Movement Control: Dedicated or Distributed?

Neural networks in which 'commands' spread 'horizontally' across multiple neurons have been believed to mediate motor pattern variation. A recent study shows that dedicated 'vertical' neural pathways can also underlie these variations.
