Visual Genome是一个针对图片描述的数据集。通过两个数据集的对比可以发现,ActivityNet Captions的描述中包含更多的动词,表明ActivityNet Captions更针对事件描述,而Visual Genome更针对物体描述。 图4 本图展示了本文模型的结果。最左侧是输入视频,然后以此是Ground Truth,不使用上下文信息的结果和使用上下文信息的结果。
Dense-Captioning Events in Videos 该论文对大多数自然视频中包含多种活动,如在一个“男人弹钢琴”的视频中,视频可能还会包含“另一个男人跳舞”或“人群鼓掌”。提出了一种新的模型,它能够在一次视频中识别所有事件,同时用自然语言描述检测到的事件。 的模型引入了一个现有提案模块的变体,该模块旨在捕获跨越几分钟...

However, since videos usually contain multiple in- terdependent events in context of a video-level story (i.e. episode), a single sentence may not be sufficient to describe videos. Consequently, dense video captioning task [8] has ∗This work was done during the internship program at Snap...
2017年,CVPR会议上的论文《Dense-Captioning Events in Videos》标志着DEC技术的正式兴起。该论文提出了将长视频分割成多个事件,并对每个事件生成一句话描述的思路,得益于同年发布的activityNet数据集,该数据集提供了大量已标注好的视频片段及其描述。 关键技术与方法 特征提取与事件定位 DEC技术的第一步是特征提取和事...

Dense captioning methods generally detect events in videos first and then generate captions for the individual events. Events are localized solely based on the visual cues while ignoring the associated linguistic information and context. Whereas end-to-end learning may implicitly take guidance from ...
Most natural videos contain numerous events. For example, in a video of a "man playing a piano", the video might also contain "another man dancing" or "a crowd clapping". We introduce the task of dense-captioning events, which involves both detecting and describing events in a video. We...
