AI总结:

本文针对视频异常检测领域缺乏简明综述及多场景综合数据集的问题,梳理相关模型与数据集的关联,推出含14个多视角场景的MSAD数据集,并验证其在多样监控场景异常检测研究中的价值。

摘要:

视频异常检测(VAD)在安防监控、交通监测、工业监测和医疗健康领域有着广泛应用。尽管已有大量研究投入,但目前仍缺乏能为研究人员提供深刻指导的简明综述,这类综述可作为快速参考资料,帮助研究者把握当前挑战、研究趋势与未来方向。本文提出了这样一篇综述,从多个维度梳理了相关模型与数据集,重点强调了模型与数据集之间的关键关联:数据集的质量与多样性深刻影响模型性能,而数据集的开发也会适配新兴方法不断演变的需求。本综述指出了当前的实际问题,包括缺乏涵盖多样场景的综合性数据集。为解决这一问题,我们推出了一个新数据集——Multi-Scenario Anomaly Detection(MSAD,多场景异常检测数据集),它包含从不同相机视角采集的14个 distinct 场景,具备多样的运动模式以及光照、天气条件等具有挑战性的变化因素,为训练性能更优的模型提供了坚实基础。我们使用MSAD对近年代表性模型开展了深入分析,凸显了该数据集在应对多样且不断变化的监控场景下的异常检测挑战方面的潜力。[项目主页:https://msad-dataset.github.io/]

英文摘要:

Video Anomaly Detection (VAD) finds widespread applications in security surveillance, traffic monitoring, industrial monitoring, and healthcare. Despite extensive research efforts, there remains a lack of concise reviews that provide insightful guidance for researchers. Such reviews would serve as quick references to grasp current challenges, research trends, and future directions. In this paper, we present such a review, examining models and datasets from various perspectives. We emphasize the critical relationship between model and dataset, where the quality and diversity of datasets profoundly influence model performance, and dataset development adapts to the evolving needs of emerging approaches. Our review identifies practical issues, including the absence of comprehensive datasets with diverse scenarios. To address this, we introduce a new dataset, Multi-Scenario Anomaly Detection (MSAD), comprising 14 distinct scenarios captured from various camera views. Our dataset has diverse motion patterns and challenging variations, such as different lighting and weather conditions, providing a robust foundation for training superior models. We conduct an in-depth analysis of recent representative models using MSAD and highlight its potential in addressing the challenges of detecting anomalies across diverse and evolving surveillance scenarios.
