Abstract

Object detection networks have achieved impressive results, but it can be challenging to replicate this success in practical applications due to a lack of relevant data specific to the task. Typically, additional data sources are used to support the training process. However, the domain gaps between these data sources present a challenge. Adversarial image-to-image style transfer is often used to bridge this gap, but it is not directly connected to the object detection task and can be unstable. We propose AWADA, a framework that combines attention-weighted adversarial domain adaptation connecting style transfer and object detection. By using object detector proposals to create attention maps for foreground objects, we focus the style transfer on these regions and stabilize the training process. Our results demonstrate that AWADA can reach state-of-the-art unsupervised domain adaptation performance in three commonly used benchmarks.

AWADA:用于跨域物体检测的前景对抗学习
物体检测网络已经取得了令人瞩目的成果,但由于缺乏任务所需的相关数据,要在实际应用中复制这种成功具有挑战性。通常情况下,会使用额外的数据源来支持训练过程。然而,这些数据源之间的领域差距是一个挑战。对抗性图像到图像风格转移通常用于弥合这一差距,但它与物体检测任务没有直接联系,而且可能不稳定。我们提出的 AWADA 是一个将注意力加权对抗域适应与风格转移和物体检测相结合的框架。通过使用对象检测器建议来创建前景对象的注意力地图,我们将风格转移集中在这些区域,并稳定了训练过程。我们的研究结果表明,AWADA 可以在三个常用基准中达到最先进的无监督领域适应性能。

期刊介绍: The central focus of this journal is the computer analysis of pictorial information. Computer Vision and Image Understanding publishes papers covering all aspects of image analysis from the low-level, iconic processes of early vision to the high-level, symbolic processes of recognition and interpretation. A wide range of topics in the image understanding area is covered, including papers offering insights that differ from predominant views. Research Areas Include: • Theory • Early vision • Data structures and representations • Shape • Range • Motion • Matching and recognition • Architecture and languages • Vision systems
