    Novel video anomaly detection method based on global-local self-attention network by Jing YANG, Chengmao WU, Liuping ZHOU

    Published 2023-08-01
    “…In order to improve the accuracy of video anomaly detection, a novel video anomaly detection method based on global-local self-attention network was proposed.Firstly, the video sequence and the corresponding RGB sequence were fused to highlight the motion change of the object.Secondly, the temporal correlation of the video sequence in the local area was captured by the expansion convolution layer, along with the self-attention network was utilized to compute the global temporal dependencies of the video sequence.Meanwhile, by deepening the basic network U-Net and combining the relevant motion and representation constraints, the network model was trained end-to-end to improve the detection accuracy and robustness of the model.Finally, experiments were carried out on the public data sets UCSD Ped2, CUHK Avenue and ShanghaiTech, as well as the test results were visually analyzed.The experimental results show that the detection accuracy AUC of the proposed method reaches 97.4%, 86.8% and 73.2% respectively, which is obviously better than that of the compared methods.…”

    Research and implementation of network architecture of LSN DCI EVPN VxLAN by Yongming YAN, Liang ZUO, Bin XU, Haifeng XU, Kechuang YE

    Published 2017-06-01
    “…With the rise of virtualization technology,the architecture of traditional data center is disrupted.There exit a large number of interconnected needs among the data centers,such as data center active-active,data center redundancy,data synchronous backup,data migration,integrated data store,shared virtual resource pool,virtual machine drift and so on.Thereby,a large amount of east-west flow was generated,it is necessary to build a reliable,flexible,secure,and easy to deploy layer-2 and layer-3 network to meet the requirement of DCI (data center interconnection).The network architecture of EVPN VxLAN was analyzed,there hasn’t been successful large-scale business case for implementation of multi-vendor DCI EVPN VxLAN networking.Combined with current status of LSN data center of Shanghai Telecom,the deployment of DCI via existing network was proposed and achieved.…”
