📝 摘要(中文)

开放词汇检测(OVD)通过文本类别查询识别训练期间未见的类别,但在实现强泛化和实时效率方面仍面临挑战。现有的实时OVD方法主要强调词汇覆盖和高效的区域/查询-文本匹配,但在严格的效率约束下,紧凑型检测器可能难以吸收丰富的实例语义和场景上下文。本文提出RT-DETR-World,一个紧凑的DETR风格检测器,能够在推理时保持轻量级的查询-文本匹配,同时转移训练期间描述所传达的丰富语义。我们构建了GroundingCapv2,采用三层监督机制,帮助紧凑型检测器吸收这些语义。实验结果表明,该方法在零-shot准确率上具有竞争力,并在准确性和效率之间取得了良好的平衡。

🔬 方法详解

问题定义:本文旨在解决开放词汇检测(OVD)中实时性与强泛化能力的矛盾。现有方法在处理未见类别时,往往难以有效利用丰富的视觉-语义线索,导致性能不足。

核心思路:RT-DETR-World通过引入丰富的训练描述和双路径描述对齐(DDA)机制,帮助紧凑型检测器在推理时吸收更多语义信息。MiniLM提供查询-类别监督,而离线教师特征则在对象和图像层面上监督匹配查询和全局视觉表示。

技术框架:该方法的整体架构包括三个主要模块:GroundingCapv2用于提供多层次的语义监督,DDA用于对齐描述与检测器的输出,RNR用于放宽负样本的约束。

关键创新:最重要的创新在于引入了双路径描述对齐机制和关系感知负放松(RNR),使得检测器能够在保持高效性的同时,充分利用训练期间的丰富语义信息。

关键设计:在设计上,使用了MiniLM作为部署一致的路径,教师模块在训练后被移除,确保了模型的轻量化。此外,采用的损失函数和特征对齐策略经过精心设计,以最大化语义信息的利用。

📄 摘要(原文)

Open-vocabulary detection (OVD) recognizes categories unseen during training through textual category queries, yet achieving strong generalization with real-time efficiency remains challenging. Beyond vocabulary scaling, zero-shot generalization may benefit from reusable visual--semantic cues learned from seen data, including attributes, actions, states, and contextual relations. Existing real-time OVD methods primarily emphasize vocabulary coverage and efficient region/query--text matching; under strict efficiency constraints, compact detectors may struggle to absorb rich instance semantics and scene context. We propose RT-DETR-World, a compact DETR-style detector that transfers the rich semantics conveyed by descriptions during training while retaining lightweight query--text matching at inference. We construct GroundingCapv2 with three levels of supervision: category names for standard OVD, object descriptions conveying instance-level semantics, and image descriptions conveying object relations and scene context. These descriptions serve only as training-time semantic supervision. To help the compact detector absorb these semantics, we propose Dual-Path Description Alignment (DDA), combining a deployment-consistent MiniLM pathway with a training-only LLM teacher. MiniLM provides query--category supervision and object-description alignment, while offline teacher features supervise matched queries and global visual representations at the object and image levels, respectively. All teacher features are precomputed, and the teacher-side modules are removed after training. We further propose Relation-Aware Negative Relaxation (RNR), which uses teacher-derived semantic similarities to relax related negatives while preserving exact positives. Experiments demonstrate competitive zero-shot accuracy and a favorable accuracy--efficiency trade-off. The code will be released.
