摘要:

计算机视觉是利用机器理解和分析图像的过程,是人工智能的一个重要分支。在CV的各个研究领域中,细粒度图像分析(FGIA)是一个长期存在的基本问题,并已在各种现实世界的应用中无处不在。FGIA的任务是分析从属类别的视觉对象,\eg,鸟类或汽车模型。细粒度性质导致的小的类间变化和大的类内变化使其成为一个具有挑战性的问题。随着深度学习的蓬勃发展,近年来,使用深度学习技术的FGIA取得了显着进展。在本文中,我们的目的是给一个系统的方式在FGIA技术的最新进展的深度学习的调查。具体来说,我们组织现有的研究FGIA技术分为三大类:细粒度的图像识别,细粒度的图像检索和细粒度的图像生成。此外,我们还涵盖了FGIA的一些其他重要问题,例如公开可用的基准数据集及其相关的特定领域应用程序。最后,我们总结了这次调查,强调了几个方向和开放的问题,需要进一步探讨的社会在未来。

英文摘要:

Computer vision (CV) is the process of using machines to understand and analyze imagery, which is an integral branch of artificial intelligence. Among various research areas of CV, fine-grained image analysis (FGIA) is a longstanding and fundamental problem, and has become ubiquitous in diverse real-world applications. The task of FGIA targets analyzing visual objects from subordinate categories, \eg, species of birds or models of cars. The small inter-class variations and the large intra-class variations caused by the fine-grained nature makes it a challenging problem. During the booming of deep learning, recent years have witnessed remarkable progress of FGIA using deep learning techniques. In this paper, we aim to give a survey on recent advances of deep learning based FGIA techniques in a systematic way. Specifically, we organize the existing studies of FGIA techniques into three major categories: fine-grained image recognition, fine-grained image retrieval and fine-grained image generation. In addition, we also cover some other important issues of FGIA, such as publicly available benchmark datasets and its related domain specific applications. Finally, we conclude this survey by highlighting several directions and open problems which need be further explored by the community in the future.
