摘要:
作为多源信息融合在智能交通感知系统中的重要应用,指代性多目标跟踪(RMOT)涉及基于语言指代在视频序列中定位和跟踪特定目标。然而,现有的RMOT方法通常将语言描述视为整体嵌入,难以将语言表达中包含的丰富语义信息与视觉特征有效整合。在需要综合理解静态目标属性和空间运动信息的复杂场景中,这一局限性尤为明显。在本文中,我们提出了一种面向指代性多目标跟踪的认知解耦(CDRMT)框架来解决这些挑战。它将人类视觉处理系统中的“what”和“where”通路适配到RMOT任务中。具体而言,我们的框架首先建立跨模态连接,同时保留模态特定的特征。然后,它解耦语言描述并将其分层注入到目标查询中,从粗粒度到细粒度的语义层面细化目标理解。最后,我们基于视觉特征重构语言表示,确保被跟踪的目标忠实地反映指代表达。在不同基准数据集上的大量实验表明,CDRMT相比最先进的方法取得了显著改进,在Refer-KITTI上的HOTA得分平均提升6.0%,在Refer-KITTI-V2上平均提升3.2%。我们的方法推进了RMOT领域的最先进水平,同时为多源信息融合提供了新见解。
英文摘要:
As a significant application of multi-source information fusion in intelligent transportation perception systems, Referring Multi-Object Tracking (RMOT) involves localizing and tracking specific objects in video sequences based on language references. However, existing RMOT approaches often treat language descriptions as holistic embeddings and struggle to effectively integrate the rich semantic information contained in language expressions with visual features. This limitation is especially apparent in complex scenes requiring comprehensive understanding of both static object attributes and spatial motion information. In this paper, we propose a Cognitive Disentanglement for Referring Multi-Object Tracking (CDRMT) framework that addresses these challenges. It adapts the "what" and "where" pathways from the human visual processing system to RMOT tasks. Specifically, our framework first establishes cross-modal connections while preserving modality-specific characteristics. It then disentangles language descriptions and hierarchically injects them into object queries, refining object understanding from coarse to fine-grained semantic levels. Finally, we reconstruct language representations based on visual features, ensuring that tracked objects faithfully reflect the referring expression. Extensive experiments on different benchmark datasets demonstrate that CDRMT achieves substantial improvements over state-of-the-art methods, with average gains of 6.0% in HOTA score on Refer-KITTI and 3.2% on Refer-KITTI-V2. Our approach advances the state-of-the-art in RMOT while simultaneously providing new insights into multi-source information fusion.
