gvatrack#

Performs object tracking using zero-term or short-term tracking algorithms. Zero-term tracking assigns unique object IDs and requires object detection to run on every frame. Short-term tracking allows to track objects between frames, thereby reducing the need to run object detection on each frame.

Please refer to Object Tracking for more information on the element properties.
