摘要:

近年来,以文学、发明、艺术作品等为代表的知识产权逐渐受到人们的关注。特别是随着电子商务的兴起,IP不仅代表产品设计和品牌,还代表电子商务平台上展示的图像/视频。不幸的是,一些攻击者采用一些对抗性的方法来欺骗训练有素的徽标检测模型进行侵权。为了克服这一问题,本文提出了一种新的标志检测器的基础上看和思考两次的机制,鲁棒的标志检测。该检测器与其他主流检测器不同,能够有效地检测小目标、长尾目标,并且对对抗图像具有鲁棒性。详细地说,我们将detectoRS算法扩展到具有均衡损失函数、多尺度变换和对抗性数据增强的级联模式。一系列实验结果表明,该方法能有效提高检测模型的鲁棒性。此外,我们已经将所提出的方法应用于竞争ACM MM 2021鲁棒标识检测,这是由阿里巴巴在天池平台上组织的,并赢得了前2名的36489队。代码可在https://github.com/jiaxiaojunQAQ/Robust-Logo-Detection上获得。

英文摘要:

In recent years, intellectual property (IP), which represents literary, inventions, artistic works, etc, gradually attract more and more people's attention. Particularly, with the rise of e-commerce, the IP not only represents the product design and brands, but also represents the images/videos displayed on e-commerce platforms. Unfortunately, some attackers adopt some adversarial methods to fool the well-trained logo detection model for infringement. To overcome this problem, a novel logo detector based on the mechanism of looking and thinking twice is proposed in this paper for robust logo detection. The proposed detector is different from other mainstream detectors, which can effectively detect small objects, long-tail objects, and is robust to adversarial images. In detail, we extend detectoRS algorithm to a cascade schema with an equalization loss function, multi-scale transformations, and adversarial data augmentation. A series of experimental results have shown that the proposed method can effectively improve the robustness of the detection model. Moreover, we have applied the proposed methods to competition ACM MM2021 Robust Logo Detection that is organized by Alibaba on the Tianchi platform and won top 2 in 36489 teams.
