The proposed system uses a prediction-based detection method, combined with a novel lambda architecture for iterative model updates and real-time anomaly detection. This paper evaluates the system using a real-world data set and a large synthetic data set, and compares with three baselines. The ...
Future Frame Prediction for Anomaly Detection – A New Baseline[arxiv,cvpr2018] orli 计算机视觉、视频异常检测7 人赞同了该文章 毕设题目定为视频异常检测,开坑第一篇论文阅读笔记。感谢大佬开源。 简介 在为数不多的使用GAN进行异常检测的文章中,本文是目前能找到的最新一篇利用GAN进行视频异常检测的paper。
Anomaly Detection on Testing Data 假设正常视频的未来帧可以很好地被预测出来,那么预测帧和真实图像的误差应该很小,而PSNR刚好可以衡量两张图片之间的差异,它的定义如下: 从PSNR的定义可以看出,如果两张图片相似度越高,那么PSNR越大,也就是说预测的PSNR越大代表该视频越有可能是正常视频。
This study examines the Taiwanese highway traffic behavior on consecutive holidays, with the aim of evaluating the Taiwanese freeway bureau's traffic control and management strategies. We propose a prediction-based detection method for finding highway traffic anomalies using reconciled ordinary least squa...
研究Future frame prediction for anomaly detection–a new baseline预测 为了解决先前的基于重构方法的视频异常检测过于完备的问题,导致异常样本重构过好,没有办法得到想要的结果,高盛华团队提出了基于预测的方法,并且首次引入了光流网络flownet就行了约束,使得预测的结果符合逾期。此外对抗性网络GAN的出现,使预测方法得到...

There are few criteria to determine the optimal CP for anomaly detection. Therefore, this paper designs a graphic indicator of the receiver operating characteristic curve of prediction interval (ROC-PI) based on the definition of the ROC curve which can depict the trade-off between the PI width...
Area-based ow prediction:基于地图的网格分割(geohash方式等),然后使用CNN、ConvLSTM等方法进行流量预测,但这种方法不能直接作用在站点上。因为grid尺寸还能调整,过大会导致一个grid有多个站点,过小或导致大量grid不包含站点 Station-based ow prediction:last value, historical,mean, historical trend, Bayesian...
