Abstract: Recently, object detection based on deep learning has been achieved remarkable achievements and various of mature models have been proposed. However, most of these models rely on a large number of annotated training samples. Besides, in practical applications, it is often difficult to get access to large scale of high-quality annotated samples, which limits its application and popularization in specific areas. Few-shot object detection has been extensively researched taking advantage of its small dependence on the number of samples. Based on the current research, this paper reviews the current mainstream of the few-shot object detection systematically, including problem definition, mainstream methods, as well as common experimental designs. Then, it points out potential application directions. Furthermore, the generalized few-shot object detection is also briefly introduced. Finally, the paper analyzes challenges of the few-shot object detection technology and discusses corresponding countermeasures.

摘要: 近年来,以深度学习为基础的图像目标检测技术取得了显著成就,并涌现了许多成熟的检测模型,但这些模型均需要利用大量的标注样本进行训练,而在实际场景当中,往往很难获取到相应规模的高质量标注样本,从而限制了其在特定领域的应用和推广。由于对样本数量的依赖性小,小样本条件下的图像目标检测技术逐渐得到研究和发展。基于小样本图像目标检测当前的研究现状,系统阐述了主流的小样本图像目标检测的问题定义、当前主要方法及实验设计,并指出其潜在应用方向,在此基础上,简要介绍了与之相关的广义小样本目标检测,最后分析了小样本图像目标检测技术面临的挑战并探讨了应对方案。
