A technology developed at EPFL will be used to analyze NBA players

Will artificial intelligence and computer vision

revolutionize the sports industry? That's what Second Spectrum is counting on. This company uses a multi-camera system to capture and analyze the athletes' every move. The aim is to see how players pull off a great pass, for example, and to assess whether or not certain shots should have been taken. This technology was developed at EPFL and then bought by Second Spectrum last year. It has caught the attention of the largest sports leagues in the world, including the NBA, which has just sealed a seven-year deal to use it in all official games starting in 2017.

Revealing the invisible

"Our technology makes the invisible visible, providing very detailed information to the fans, the commentators and the coaches," said Dr. Horesh Ben Shitrit, who co-founded PlayfulVision together with Professor Pascal Fua and is now the Director of Computer Vision products at Second Spectrum Switzerland.

The system is based on optical trackers that capture every move by every player and by the ball, recording their exact coordinates 25 times per second. This information will be used to carefully analyze games: body position, shots, rebounds and fouls. "We provide an in-depth understanding of the games, at a greater level of detail than a coach can perceive alone," says Shitrit.
