arXiv:2403.02767v1 Announce Type: new Abstract: Accurate data association is crucial in reducing confusion, such as ID switches and assignment errors, in multi-object tracking (MOT). However, existing advanced methods often overlook the diversity among trajectories and the ambiguity and conflicts present in motion and appearance cues, leading to confusion among detections, trajectories, and associations when performing simple global data association. To address this issue, we propose a simple, versatile, and highly interpretable data association approach called Decomposed Data Association (DDA). DDA decomposes the traditional association problem into multiple sub-problems using a series of non-learning-based modules and selectively addresses the confusion in each sub-problem by incorporating targeted exploitation of new cues. Additionally, we introduce Occlusion-aware Non-Maximum Suppression (ONMS) to retain more occluded detections, thereby increasing opportunities for association with trajectories and indirectly reducing the confusion caused by missed detections. Finally, based on DDA and ONMS, we design a powerful multi-object tracker named DeconfuseTrack, specifically focused on resolving confusion in MOT. Extensive experiments conducted on the MOT17 and MOT20 datasets demonstrate that our proposed DDA and ONMS significantly enhance the performance of several popular trackers. Moreover, DeconfuseTrack achieves state-of-the-art performance on the MOT17 and MOT20 test sets, significantly outperforms the baseline tracker ByteTrack in metrics such as HOTA, IDF1, AssA. This validates that our tracking design effectively reduces confusion caused by simple global association.

Introducing a Revolutionary Approach to Data Association: DeconfuseTrack
Data association plays a crucial role in multi-object tracking (MOT), as it helps reduce confusion, such as ID switches and assignment errors. However, existing advanced methods often fall short when it comes to addressing the diversity among trajectories and the ambiguity and conflicts present in motion and appearance cues, resulting in confusion among detections, trajectories, and associations during simple global data association. To tackle this issue head-on, we present an innovative and highly effective data association approach called Decomposed Data Association (DDA).
DDA takes a unique approach by breaking down the traditional association problem into multiple sub-problems using a series of non-learning-based modules. Instead of treating all cues and trajectories equally, DDA selectively addresses confusion in each sub-problem by incorporating targeted exploitation of new cues. This selective approach allows for a more nuanced understanding of the underlying dynamics, leading to more accurate data association.
One of the major challenges in data association is dealing with occlusions. Missed or incorrectly assigned detections due to occlusions can significantly impact the overall tracking performance. To overcome this challenge, we introduce a novel technique called Occlusion-aware Non-Maximum Suppression (ONMS). ONMS helps retain more occluded detections, increasing the opportunities for association with trajectories. By indirectly reducing the confusion caused by missed detections, ONMS further enhances the performance of data association.
Building upon DDA and ONMS, we have developed a powerful multi-object tracker known as DeconfuseTrack. Unlike traditional trackers that solely rely on simple global data association, DeconfuseTrack takes a comprehensive approach, leveraging the benefits of DDA and ONMS to resolve confusion in MOT. Our aim is to provide a more accurate and robust tracking solution that outperforms existing trackers.
We conducted extensive experiments using the MOT17 and MOT20 datasets to evaluate the performance of DDA and ONMS. The results speak for themselves – our proposed approach significantly enhances the performance of several popular trackers. Additionally, DeconfuseTrack achieves state-of-the-art performance on the MOT17 and MOT20 test sets, surpassing the baseline tracker ByteTrack across various metrics such as HOTA, IDF1, and AssA. These results validate that our tracking design effectively reduces confusion caused by simple global association.
In conclusion, the introduction of DDA, ONMS, and DeconfuseTrack brings forth a new era in data association for multi-object tracking. By recognizing the diversity among trajectories, addressing confusion through selective exploitation of cues, and providing robust occlusion handling, our approach sets a new standard for tracking performance. We believe that the proposed innovations will pave the way for more accurate and reliable multi-object tracking systems in the future.
The paper titled “Accurate Data Association in Multi-Object Tracking with Decomposed Data Association” introduces a new approach called Decomposed Data Association (DDA) to address the challenge of confusion in multi-object tracking (MOT). The authors highlight that existing advanced methods often overlook the diversity among trajectories and the ambiguity and conflicts present in motion and appearance cues, leading to confusion in data association.
DDA decomposes the traditional association problem into multiple sub-problems using a series of non-learning-based modules. By doing so, it selectively addresses the confusion in each sub-problem by incorporating targeted exploitation of new cues. This approach allows for a more nuanced understanding and handling of the complexity involved in MOT, which can lead to improved accuracy.
Additionally, the authors introduce Occlusion-aware Non-Maximum Suppression (ONMS) to retain more occluded detections. This is crucial as occlusions often lead to missed detections, which in turn can cause confusion in data association. By retaining more occluded detections, DeconfuseTrack (the multi-object tracker designed based on DDA and ONMS) increases opportunities for association with trajectories, indirectly reducing confusion caused by missed detections.
The authors conducted extensive experiments on the MOT17 and MOT20 datasets to evaluate the performance of DDA and ONMS. The results demonstrate that the proposed approach significantly enhances the performance of several popular trackers. Furthermore, DeconfuseTrack achieves state-of-the-art performance on the MOT17 and MOT20 test sets, outperforming the baseline tracker ByteTrack in metrics such as HOTA, IDF1, and AssA. This validates that the tracking design effectively reduces confusion caused by simple global association.
Overall, this research presents a promising approach to address the challenge of confusion in multi-object tracking. By decomposing the data association problem and incorporating targeted exploitation of new cues, the proposed method shows improved performance compared to existing trackers. Future research could focus on exploring the scalability and generalizability of DDA and ONMS across different datasets and scenarios, as well as investigating the potential for incorporating learning-based modules to further enhance the accuracy of data association in MOT.
