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 for tracking objects between frames, reducing the need to run object detection on each frame. Imageless tracking forms object associations based on the movement and shape of objects, and does not use image data.

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