AI总结:

本研究探索利用大语言模型协调多个视觉语言模型,在仅依赖少量关键帧和弱时序信息的情况下进行监控视频动作识别,实验验证了可行性,并建议增强时序信号和帧数以提升性能。

摘要:

近年来的进展引入了多个视觉语言模型(VLMs),这些模型在多个领域展示了令人印象深刻的常识推理能力。尽管它们各自具备能力,但将这些互补的视觉语言模型协同起来的潜力仍未得到充分探索。Cola框架通过展示大语言模型(LLM)如何通过自然语言通信高效协调多个视觉语言模型,利用它们各自不同的优势,解决了这一问题。我们在具有挑战性的A-OKVQA数据集上验证了这一主张,确认了这种协调的有效性。在此基础上,我们的研究探讨了相同的方法能否应用于监控视频中的动作识别。具体而言,我们探索了在仅提供少量选择性重要帧和最小时序信息的情况下,利用视觉语言模型和大语言模型的组合知识库能否有效从视频中推断出动作。我们的实验表明,尽管时序信号较弱,大语言模型在协调不同视觉语言模型时,仍能在各种场景中成功识别模式并推断出动作。然而,我们的研究结果表明,为了将这种方法提升为一种可行的替代解决方案,整合更强的时序信号并让模型接触更多帧将是有益的。

英文摘要:

Recent advancements have introduced multiple vision-language models (VLMs) demonstrating impressive commonsense reasoning across various domains. Despite their individual capabilities, the potential of synergizing these complementary VLMs remains underexplored. The Cola Framework addresses this by showcasing how a large language model (LLM) can efficiently coordinate multiple VLMs through natural language communication, leveraging their distinct strengths. We have verified this claim on the challenging A-OKVQA dataset, confirming the effectiveness of such coordination. Building on this, our study investigates whether the same methodology can be applied to surveillance videos for action recognition. Specifically, we explore if leveraging the combined knowledge base of VLMs and LLM can effectively deduce actions from a video when presented with only a few selectively important frames and minimal temporal information. Our experiments demonstrate that LLM, when coordinating different VLMs, can successfully recognize patterns and deduce actions in various scenarios despite the weak temporal signals. However, our findings suggest that to enhance this approach as a viable alternative solution, integrating a stronger temporal signal and exposing the models to slightly more frames would be beneficial.
