基于查询引导和语义增强的小样本目标检测方法OA
Few-shot Object Detection Method Based on Query Guidance and Semantic Enhancement
针对元学习范式中原型关键信息欠缺、对查询图像适应性不足以及检测器对新类方差敏感导致误分类问题,提出一种基于查询引导策略和语义增强机制的小样本目标检测(FSOD)方法.查询引导模块(QGM)通过学习查询与支持特征之间的相关性,将查询感知信息有条件地耦合到支持特征中,旨在为每个查询图像生成特定且具有代表性的原型.而视觉语义增强模块(VSEM)从文本语义信息中蒸馏与新类视觉特征相匹配的知识,并自适应地对这些特征增强,提高其可判别性,缓解方差敏感,以更好地分类.此外,将分类和回归任务解耦,在分类分支上执行语义增强,以促进模型对目标语义的理解.实验结果表明,相较于目前已知最新的SMPCCNet方法,所提出方法在PASCAL VOC数据集上的新类平均精度(nAP)提升了 2.2百分点,在MS COCO数据集上的平均精度(AP)提升了 1.0百分点,证明了其有效性.
This study proposes a Few-Shot Object Detection(FSOD)method based on a query-guided strategy and semantic enhancement mechanism to address the following concerns:the lack of prototypical key information,insufficient adaptation to query images in the meta-learning paradigm,and the detector's sensitivity to the variance of the novel class leading to misclassification.The Query Guidance Module(QGM)conditionally couples query-aware information into support features by learning the correlation between the query and support features,aiming to generate specific and representative prototypes for each query image.The Visual Semantic Enhancement Module(VSEM)distils the knowledge from textual semantic information that matches the novel class of visual features and adaptively enhances these features to improve their discriminability and mitigate variance sensitivity for better classification.In addition,the classification and regression tasks are decoupled,and semantic enhancement is performed on the classification branch to facilitate the model's understanding of the target semantics.The experimental results demonstrate that,compared to the currently known state-of-the-art SMPCCNet method,the proposed approach achieves an average improvement of 2.2 percentage points in novel Average Precision(nAP)on the PASCAL VOC dataset and an average improvement of 1.0 percentage points in Average Precision(AP)on the MS COCO dataset,validating its effectiveness.
