HOTA (Higher Order Tracking Accuracy) is a novel metric for evaluating multi-object tracking (MOT) performance. It is designed to overcome many of the limitations of previous metrics such as MOTA, IDF1 and Track mAP.

This short blog post gives an overview of the most important aspects of HOTA in three parts:

1. How to calculate the HOTA metrics.

2. How to compare trackers with the HOTA metrics.

3. How does HOTA compare to alternative tracking metrics.

For more details on HOTA, check out the IJCV 2020 paper and the metrics code on GitHub.
