AI总结:

VANE-Bench是一个新基准,用于评估视频大语言模型在检测和定位视频异常(如非自然变换、消失等)方面的能力,发现现有模型在此任务上表现不佳。

摘要:

大型多模态视频模型(Video-LMMs)的最新发展显著增强了我们解释和分析视频数据的能力。尽管其能力令人印象深刻,但当前的Video-LMMs尚未针对异常检测任务进行评估,而这对它们在实践场景中的部署至关重要,例如识别深度伪造、篡改视频内容、交通事故和犯罪。在本文中,我们引入了VANE-Bench,一个旨在评估Video-LMMs在检测和定位视频中异常与不一致性方面熟练度的基准。我们的数据集包含使用现有最先进的文本到视频生成模型合成生成的一系列视频,涵盖了五类细微异常和不一致性:非自然变换、非自然外观、穿透、消失和突然出现。此外,我们的基准还包含来自现有异常检测数据集的真实世界样本,重点关注与犯罪相关的不规则行为、非典型行人行为和异常事件。该任务被构建为视觉问答挑战,以衡量模型准确检测和定位视频中异常的能力。我们在此基准任务上评估了九个现有的Video-LMMs,包括开源和闭源模型,并发现大多数模型在有效识别细微异常方面遇到困难。总之,我们的研究为Video-LMMs在异常检测领域的当前能力提供了重要见解,突显了我们在评估和改进这些模型以用于现实世界应用方面的工作的重要性。我们的代码和数据可在https://hananshafi.github.io/vane-benchmark/获取。

英文摘要:

The recent developments in Large Multi-modal Video Models (Video-LMMs) have significantly enhanced our ability to interpret and analyze video data. Despite their impressive capabilities, current Video-LMMs have not been evaluated for anomaly detection tasks, which is critical to their deployment in practical scenarios e.g., towards identifying deepfakes, manipulated video content, traffic accidents and crimes. In this paper, we introduce VANE-Bench, a benchmark designed to assess the proficiency of Video-LMMs in detecting and localizing anomalies and inconsistencies in videos. Our dataset comprises an array of videos synthetically generated using existing state-of-the-art text-to-video generation models, encompassing a variety of subtle anomalies and inconsistencies grouped into five categories: unnatural transformations, unnatural appearance, pass-through, disappearance and sudden appearance. Additionally, our benchmark features real-world samples from existing anomaly detection datasets, focusing on crime-related irregularities, atypical pedestrian behavior, and unusual events. The task is structured as a visual question-answering challenge to gauge the models' ability to accurately detect and localize the anomalies within the videos. We evaluate nine existing Video-LMMs, both open and closed sources, on this benchmarking task and find that most of the models encounter difficulties in effectively identifying the subtle anomalies. In conclusion, our research offers significant insights into the current capabilities of Video-LMMs in the realm of anomaly detection, highlighting the importance of our work in evaluating and improving these models for real-world applications.
