论文摘要
在现实世界中,人重新识别(RE-ID)仍然具有挑战性,因为它需要一个受过训练的网络在跨域之间存在变化的情况下概括以完全看不见的目标数据。最近,已经广泛采用了生成对抗模型,以增强培训数据的多样性。但是,这些方法通常无法推广到其他领域,因为现有的生成人员重新识别模型在生成组件和歧视性特征学习阶段之间具有脱节。为了解决有关模型概括的持续挑战,我们提出了一个端到端域自适应注意网络,以在单个框架中共同翻译域之间的图像并学习歧视性重新ID特征。为了应对域间隙挑战,我们引入了一个关注模块,用于从源到目标域的图像翻译,而不会影响人的身份。更具体地说,注意是指向背景,而不是人的整个形象,以确保保留对象的特征。拟议的联合学习网络可在几个基准数据集上对最先进的方法进行显着改善。
Person re-identification (re-ID) remains challenging in a real-world scenario, as it requires a trained network to generalise to totally unseen target data in the presence of variations across domains. Recently, generative adversarial models have been widely adopted to enhance the diversity of training data. These approaches, however, often fail to generalise to other domains, as existing generative person re-identification models have a disconnect between the generative component and the discriminative feature learning stage. To address the on-going challenges regarding model generalisation, we propose an end-to-end domain adaptive attention network to jointly translate images between domains and learn discriminative re-id features in a single framework. To address the domain gap challenge, we introduce an attention module for image translation from source to target domains without affecting the identity of a person. More specifically, attention is directed to the background instead of the entire image of the person, ensuring identifying characteristics of the subject are preserved. The proposed joint learning network results in a significant performance improvement over state-of-the-art methods on several benchmark datasets.
