摘要:

在传统的人物Re-ID设置中,广泛地假设裁剪的人物图像是针对每个个体的。然而,在拥挤的场景中,现成的检测器可能会生成涉及多个人的边界框,其中存在大比例的背景行人或人类遮挡。从这样的裁剪图像中提取的表示,其中包含目标和干扰行人,可能包括分心的信息。这将导致错误的检索结果。为了解决这个问题,本文提出了一种新的深度网络,称为行人干扰抑制网络(PISNet)。PISNet利用查询引导注意块(QGAB)在查询的指导下增强图库中目标的功能。此外,引导反向注意模块和多人分离损失的参与促进QGAB抑制其他行人的干扰。我们的方法进行了评估两个新的干扰数据集,结果表明,该方法优于现有的Re-ID方法。

英文摘要:

In the conventional person Re-ID setting, it is widely assumed that cropped person images are for each individual. However, in a crowded scene, off-shelf-detectors may generate bounding boxes involving multiple people, where the large proportion of background pedestrians or human occlusion exists. The representation extracted from such cropped images, which contain both the target and the interference pedestrians, might include distractive information. This will lead to wrong retrieval results. To address this problem, this paper presents a novel deep network termed Pedestrian-Interference Suppression Network (PISNet). PISNet leverages a Query-Guided Attention Block (QGAB) to enhance the feature of the target in the gallery, under the guidance of the query. Furthermore, the involving Guidance Reversed Attention Module and the Multi-Person Separation Loss promote QGAB to suppress the interference of other pedestrians. Our method is evaluated on two new pedestrian-interference datasets and the results show that the proposed method performs favorably against existing Re-ID methods.
