• Abstract summary: Multi-Object Tracking (MOT) aims to associate multiple objects across video frames. Most existing approaches train and track within a single domain, resulting in a lack of cross-domain generalizability. We develop IP-MOT, an end-to-end transformer model for MOT that operates without concrete textual descriptions.

• Abstract: Multi-Object Tracking (MOT) aims to associate multiple objects across video frames and is a challenging vision task due to inherent complexities in the tracking environment. Most existing approaches train and track within a single domain, resulting in a lack of cross-domain generalizability to data from other domains. While several works have introduced natural language representation to bridge the domain gap in visual tracking, these textual descriptions often provide too high-level a view and fail to distinguish various instances within the same class. In this paper, we address this limitation by developing IP-MOT, an end-to-end transformer model for MOT that operates without concrete textual descriptions. Our approach is underpinned by two key innovations: Firstly, leveraging a pre-trained vision-language model, we obtain instance-level pseudo textual descriptions via prompt-tuning, which are invariant across different tracking scenes; Secondly, we introduce a query-balanced strategy, augmented by knowledge distillation, to further boost the generalization capabilities of our model. Extensive experiments conducted on three widely used MOT benchmarks, including MOT17, MOT20, and DanceTrack, demonstrate that our approach not only achieves competitive performance on same-domain data compared to state-of-the-art models but also significantly improves the performance of query-based trackers by large margins for cross-domain inputs.

At inference, our LG-MOT uses the standard visual features without relying on annotated language descriptions. Our LG-MOT achieves an absolute gain of 2.2% in terms of target object association (IDF1 score) compared to the baseline using only visual features.

• Generalizing Multiple Object Tracking to Unseen Domains by Introducing Natural Language Representation [33.03600813115465]
  We propose to introduce natural language representation into visual MOT models for boosting the domain generalization ability. To tackle this problem, we design two modules, namely visual context prompting (VCP) and visual-language mixing (VLM) VLM joints the information in the generated visual prompts and the textual prompts from a pre-defined Trackbook to obtain instance-level pseudo textual description. Through training models on MOT17 and validating them on MOT20, we observe that the pseudo textual descriptions generated by our proposed modules improve the generalization performance of query-based trackers by large margins.

  Multiple-object tracking (MOT) is a challenging task that requires simultaneous reasoning about location, appearance, and identity of the objects in the scene over time. Our aim in this paper is to move beyond tracking-by-detection approaches, to class-agnostic tracking that performs well also for unknown object classes.
