gvatrack
========

Performs object tracking using zero-term, zero-term-imageless, or short-term-imageless 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. 
Imageless tracking forms object associations based on the movement and shape of objects, and it does not use image data.

Please refer to :doc:`Object Tracking <../dev_guide/object_tracking>` for more
information on the element properties.
