AI总结:

本文针对长视频检索中未见词汇与场景的挑战,提出融合视觉、听觉及字幕分割的统一框架,并设计长视频专用评估指标,在YouCook2上验证了有效性。

摘要:

精确的视频检索需要多模态关联来处理未见过的词汇和场景,对于长视频而言,模型必须在没有针对特定数据集进行预训练的情况下有效运行,这使得问题更加复杂。我们提出一个统一框架,将视觉匹配流和听觉匹配流与一种独特的基于字幕的视频分割方法相结合。此外,听觉流包含一个互补的基于音频的两阶段检索机制,以提升长时视频上的性能。考虑到长视频检索及其相应评估的复杂性,我们引入一种专为长视频检索设计的新型检索评估方法,以支持进一步研究。我们在YouCook2基准上进行了实验,展示了有前景的检索性能。

英文摘要:

Precise video retrieval requires multi-modal correlations to handle unseen vocabulary and scenes, becoming more complex for lengthy videos where models must perform effectively without prior training on a specific dataset. We introduce a unified framework that combines a visual matching stream and an aural matching stream with a unique subtitles-based video segmentation approach. Additionally, the aural stream includes a complementary audio-based two-stage retrieval mechanism that enhances performance on long-duration videos. Considering the complex nature of retrieval from lengthy videos and its corresponding evaluation, we introduce a new retrieval evaluation method specifically designed for long-video retrieval to support further research. We conducted experiments on the YouCook2 benchmark, showing promising retrieval performance.
