该论文解决的目标实际上是“Spatio-Temporal Action Grounding”,任务目标实际上落在行为或动作本身,其可能对应了多个参与实体和区域; 考虑到global feature和local feature的聚合程度和粒度,文章使用这两组特征对temporal grounding和spatial grounding分开建模; 文章尝试在没有时空标注仅有ASR转录的视频数据集(HowTo100M)...
Video temporal groundingCo-interactive transformerMulti-modal feature fusionLanguage-guided video temporal grounding is to temporally localize the best matched video segment in an untrimmed long video according to a given natural language query (sentence). The main challenge in this task lies in how ...
传统的方法将grounding看作一个基于检测的回归问题,通过在视频上预先划定一系列的时域锚框,然后在模态融合之后预测不同锚框的置信度和偏移量。这类方法的缺点是难以建立视频的时序前后关系。比如如下一个视频,如果不建立时序关系,只进行简单的匹配,是很难分辨第一段和第三段的。 一、2D-TAN Learning 2D Temporal Ad...
Video Temporal Grounding (VTG) focuses on accurately identifying event timestamps within a particular video based on a linguistic query, playing a vital role in downstream tasks such as video browsing and editing. While Video Large Language Models (video LLMs) have made significant progress in und...

Video Temporal Grounding (VTG) aims to ground specific segments within an untrimmed video corresponding to the given natural language query. Existing VTG methods largely depend on supervised learning and extensive annotated data, which is labor-intensive and prone to human biases. To address these cha...
Video Temporal Grounding (VTG), which aims to ground target clips from videos (such as consecutive intervals or disjoint shots) according to custom language queries (e.g., sentences or words), is key for video browsing on social media. Most methods in this direction develop taskspecific models...

We address the problem of text-guided video temporal grounding, which aims to identify the time interval of a certain event based on a natural language description. Different from most existing methods that only consider RGB images as visual features, we propose a multi-modal framework to extract...
