Time-series Meets Complex Motion Modeling: Robust and Computational-effective Motion Predictor for Multi-object Tracking

- 基于改进的时序卷积网络,支持任意长度上下文建模
- 在HOTA、IDF1、AssA上全面超越当前最优方法
- 参数量和计算量仅为现有方法的1.4%和5%,适合实时应用
多目标跟踪(MOT)在安防、自动驾驶和机器人等领域至关重要。准确预测物体运动是MOT的基础,但现有方法在应对真实世界非线性运动(如急停、急转弯)时表现不佳。尽管近期研究趋向于复杂且高耗能的生成模型,其实际应用受限。本文提出一种更高效、专为运动预测设计的框架——时序卷积运动预测器(TCMP),采用带膨胀卷积的时序卷积网络结构与回归头,可灵活处理任意时间上下文。实验表明,该方法在多个关键指标上达到新纪录:HOTA从62.3%提升至63.4%,IDF1从63.0%增至65.0%,AssA从47.2%提高到49.1%。更重要的是,TCMP仅需0.014倍参数量和0.05倍计算量(FLOPs),相较当前最优方法显著降低资源开销。结果证明该方法在复杂场景中兼具鲁棒性、准确性与效率。
原文摘要 · Abstract (English)
Multi-object tracking (MOT) is critical in numerous real-world applications, including surveillance, autonomous driving, and robotics. Accurately predicting object motion is fundamental to MOT, but current methods struggle with the complexities of real-world, non-linear motion (e.g., sudden stops, sharp turns). While recent research has gravitated towards increasingly complex and computationally expensive generative models to tackle this problem, their practical utility is often constrained. This paper challenges that paradigm, arguing that such complexity is not only unnecessary but can be outperformed by a more efficient, purpose-built approach. We introduce the Temporal Convolutional Motion Predictor (TCMP), a novel framework for MOT that leverages a modified Temporal Convolutional Network (TCN) featuring dilated convolutions and a regression head. This design allows for effective motion prediction across arbitrary temporal context lengths. Experimental results demonstrate that our approach achieves state-of-the-art performance, specifically improves upon the previous best method in several key metrics: HOTA (a measure of overall tracking accuracy) increases from 62.3% to 63.4%, IDF1 (a measure of identity preservation) rises from 63.0% to 65.0%, and AssA (a measure of association accuracy) improves from 47.2% to 49.1%. Significantly, TCMP achieves this performance while being highly efficient; it has only 0.014 times the parameters and requires only 0.05 times the computational cost (FLOPs) compared to the SOTA method. while is only 0.014 times the size (in terms of parameters) and requires only 0.05 times the computational cost (in terms of FLOPs). These findings highlight the robustness of our method to advance MOT systems by ensuring adaptability, accuracy, and efficiency in complex tracking environments.
