This year's Olympic Games in Tokyo use an advanced three-dimensional (3D) tracking system that captures athletes' performances in fine detail.

Intel's 3DAT system sends live camera footage to the cloud, where artificial intelligence (AI) uses deep learning to analyze an athlete's movements and identify key performance traits like top speed and deceleration.

3DAT shares this information with viewers as slow-motion graphic representations of the action in less than 30 seconds.

Intel's Jonathan Lee and colleagues trained the AI on recorded footage of elite track and field athletes, with all body parts annotated; the model could then link the video to a simplified rendering of an athlete's form.

The AI can track this "skeleton" and calculate the position of each athlete's body in three dimensions as it moves through an event.
