Video-Based Passive Vital Signs Measurement for Sports Broadcast

Imicast Impulse™ measures an athlete's vital signs through real-time video analysis of their skin. These metrics are output through a configurable data interface to third party overlay graphics systems, for live TV broadcast and to inform commentary. They provide a great insight into an athlete's performance.

No special cameras or lighting are needed.

Imicast Impulse™ uses a patented approach based on independent component analysis (ICA) of skin colour over time. The system performs face detection and tracking to identify the area of the picture to focus on. It uses bespoke image processing optimised for sports applications, applies the ICA algorithms and then analyses the frequency components of the resultant signals to determine the heart rate and other vital signs.
