本文提出 MotionEpic 视频 MLLM 与 Video-of-Thought 框架,借助 STSG 和 CoT 实现从像素感知到认知理解的逐步视频推理,并在复杂视频问答基准上提升最先进性能。

摘要:

现有视频理解研究仍难以在复杂视频中实现深入理解与推理,主要原因在于两个关键瓶颈尚未得到充分探索:细粒度时空感知理解,以及认知层面的视频场景理解。本文通过提出一种新颖解决方案来弥合这一差距。我们首先引入一种新型视频多模态大语言模型(MLLM)MotionEpic,该模型通过整合视频时空场景图(STSG)表示,实现细粒度像素级时空视频定位。随后,在 MotionEpic 的基础上,我们开发了 Video-of-Thought(VoT)推理框架。VoT 继承了思维链(CoT)的核心,将复杂任务分解为更简单、可处理的子问题,并从低层像素感知到高层认知解释逐步加以解决。在多种复杂视频问答基准上的大量实验表明,我们的整体框架显著提升了现有最先进水平。据我们所知,这是首次成功运用 CoT 技术以实现人类水平视频推理的尝试,并展现出将其扩展到更广泛视频理解场景的巨大潜力。项目已开放于 https://haofei.vip/VoT。

英文摘要:

Existing research of video understanding still struggles to achieve in-depth comprehension and reasoning in complex videos, primarily due to the under-exploration of two key bottlenecks: fine-grained spatial-temporal perceptive understanding and cognitive-level video scene comprehension. This paper bridges the gap by presenting a novel solution. We first introduce a novel video Multimodal Large Language Model (MLLM), MotionEpic, which achieves fine-grained pixel-level spatial-temporal video grounding by integrating video spatial-temporal scene graph (STSG) representation. Building upon MotionEpic, we then develop a Video-of-Thought (VoT) reasoning framework. VoT inherits the Chain-of-Thought (CoT) core, breaking down a complex task into simpler and manageable sub-problems, and addressing them step-by-step from a low-level pixel perception to high-level cognitive interpretation. Extensive experiments across various complex video QA benchmarks demonstrate that our overall framework strikingly boosts existing state-of-the-art. To our knowledge, this is the first attempt at successfully implementing the CoT technique for achieving human-level video reasoning, where we show great potential in extending it to a wider range of video understanding scenarios.
