Track bounding boxes

Track bounding boxes of the same object detection across video frames

Overview

A common issue when doing object detection on video is that detections are not associated between each camera frame. This can cause issues for use cases such as counting items in a video. In essence without tracking, each frame would would add the the count.

Implementation

We have implemented a version of ByteTrack to track object detection outputs between frames.

Usage

The most common usage is to directly connect the output of an object detection component to this component.

Using the output

The component modifies each bounding box that is passed into it and adds/updates the following fields on the bounding box.
