The system is composed of one or more nodes flexibly according to the application scenarios such as private properties  banks and museums. Each node is an autonomous vision-based device capable to perform intelligent tasks. It is able to digitize and compress the acquired analog video signals in MPEG-4 standard and then transmit the compressed video stream to the control center. At the same time  the node makes use of a statistical approach for real-time detecting moving object and online alarm generation to enable a single human operator to monitor activities over a complex area using a distributed network of active video sensors. The node is implemented on a platform with high performance to ensure that the algorithm is able to run in real-time. Applications demonstrate that the intelligent system has an excellent performance in many scenarios to help people make decisions more accurately and rapidly. 2010 IEEE.   Monitoring trail allocation for fast link failure localization without electronic alarm dissemination 会议论文 2011 作者:  Tapolcai,J.;  BinWu;  WeiHe;  Pin-HanHo 收藏  |  浏览/下载：1/0  |  提交时间：2020/01/04 telecommunication  network  reliability  greedy  algorithms  minimax  techniques  optical  fibre  networks  optical  fibre  telemetry  min  wavelength  max  information  trail  allocation  monitoring  link  failure  localization  electronic  alarm  dissemination  optical  networks  supervisory  optical  signal  optical  alarm  signals  greedy  algorithm  wavelength  division  multiplexing  All-optical  networks  fast  link  failure  localization  monitoring  trail
