How to get linear velocity from detected objects?

There’s an example showed on the Zed website about spatial object detection that displays current velocity of people on a basketball court.

How is the velocity of the detected people retrieved or calculated?

Hi @rmonroe
The velocity is extracted by estimating the status of each tracked object step by step using a Kalman filter as estimator.
The velocity is part of the available information:
