摘要:

本文的目的是文本到视频检索的任务,在给定的查询的形式,一个自然语言的句子,它被要求检索的视频语义相关的给定的查询,从大量的未标记的视频。这项任务的成功取决于跨模态表示学习,它将视频和句子投影到公共空间中进行语义相似度计算。在这项工作中,我们专注于视频表示学习,文本到视频检索的重要组成部分。受人类阅读策略的启发,本文提出了一种基于视觉表示学习的视频表示方法,该方法包括两个分支:预览分支和强化阅读分支。预览分支旨在简要捕获视频的概述信息,而精读分支旨在获得更深入的信息。此外,精读分支知道由预览分支捕获的视频概览。这样的整体信息被发现是有用的精读分支提取更细粒度的功能。在三个数据集上进行了广泛的实验,我们的模型RIVRL在TGIF和VATEX上实现了新的最先进的水平。此外,在MSR-VTT上,我们使用两个视频特征的模型显示出与使用七个视频特征的最先进模型相当的性能,甚至优于在大规模HowTo 100 M数据集上预训练的模型。

英文摘要:

This paper aims for the task of text-to-video retrieval, where given a query in the form of a natural-language sentence, it is asked to retrieve videos which are semantically relevant to the given query, from a great number of unlabeled videos. The success of this task depends on cross-modal representation learning that projects both videos and sentences into common spaces for semantic similarity computation. In this work, we concentrate on video representation learning, an essential component for text-to-video retrieval. Inspired by the reading strategy of humans, we propose a Reading-strategy Inspired Visual Representation Learning (RIVRL) to represent videos, which consists of two branches: a previewing branch and an intensive-reading branch. The previewing branch is designed to briefly capture the overview information of videos, while the intensive-reading branch is designed to obtain more in-depth information. Moreover, the intensive-reading branch is aware of the video overview captured by the previewing branch. Such holistic information is found to be useful for the intensive-reading branch to extract more fine-grained features. Extensive experiments on three datasets are conducted, where our model RIVRL achieves a new state-of-the-art on TGIF and VATEX. Moreover, on MSR-VTT, our model using two video features shows comparable performance to the state-of-the-art using seven video features and even outperforms models pre-trained on the large-scale HowTo100M dataset.
