B-on-Track: A Novel Evaluation Metric for Multiple Object Tracking

Multi-object tracking (MOT) is essential in various applications. Still, more effective evaluation metrics are often needed to measure a tracker's ability to consistently follow an object without losing track and minimize re-identification issues. Addressing this precise problem, we present B-on-Track, a novel evaluation metric formulated to gauge a tracker's competence in maintaining continuous tracking without loss and reducing re-identification challenges. By implementing and evaluating the B-on-Track metric on the MOTChallenge Benchmark, this paper thoroughly compares with existing evaluation metrics, elucidating the distinctive benefits and potential applications of the B-on-Track metric in the MOT field. Detailed interpretations of the B-on-Track metric further demonstrate its robustness and innovation in filling the existing gaps in MOT evaluation.
