摘要:

视觉问答(VQA)是一项具有挑战性的任务,越来越受到计算机视觉和自然语言处理界的关注。给定图像和自然语言中的问题,它需要对图像的视觉元素和一般知识进行推理以推断出正确的答案。在本调查的第一部分中,我们通过比较现代解决问题的方法来研究最先进的技术。我们分类的方法,他们的机制,以连接视觉和文本形式。特别是,我们研究了将卷积神经网络和递归神经网络相结合的常见方法,将图像和问题映射到一个共同的特征空间。我们还讨论了与结构化知识库接口的内存增强和模块化架构。在本调查的第二部分中,我们回顾了可用于训练和评估VQA系统的数据集。各种数据集包含不同复杂程度的问题,需要不同的推理能力和类型。我们深入研究的问题/答案对从视觉基因组项目,并评估的相关性的结构化注释的图像与场景图VQA。最后,我们讨论了有前途的未来方向的领域,特别是连接到结构化的知识库和使用自然语言处理模型。

英文摘要:

Visual Question Answering (VQA) is a challenging task that has received increasing attention from both the computer vision and the natural language processing communities. Given an image and a question in natural language, it requires reasoning over visual elements of the image and general knowledge to infer the correct answer. In the first part of this survey, we examine the state of the art by comparing modern approaches to the problem. We classify methods by their mechanism to connect the visual and textual modalities. In particular, we examine the common approach of combining convolutional and recurrent neural networks to map images and questions to a common feature space. We also discuss memory-augmented and modular architectures that interface with structured knowledge bases. In the second part of this survey, we review the datasets available for training and evaluating VQA systems. The various datatsets contain questions at different levels of complexity, which require different capabilities and types of reasoning. We examine in depth the question/answer pairs from the Visual Genome project, and evaluate the relevance of the structured annotations of images with scene graphs for VQA. Finally, we discuss promising future directions for the field, in particular the connection to structured knowledge bases and the use of natural language processing models.
