Annual Allerton Conference on Communication, Control, and Computing
作者: Manqi Zhao Venkatesh Saligrama Department of Electrical and Computer Engineering Boston University Boston MA USA
We propose a novel non-parametric adaptive outlier detection algorithm, called LPE, for high dimensional data based on score functions derived from nearest neighbor graphs on n-point nominal data. Outliers are predict... 详细信息

International Asia Conference on Informatics in Control, Automation and Robotics, CAR
作者: Yu-Kumg Chen Tung-Yi Cheng Shuo-Tsung Chiu Department of Electronic Engineering Huafan University Taipei Taiwan
The traditional automatic smart image surveillance system can usually be used in the environment with still background. That is, the background image must not contain the moving objects. If there is waving ocean, wavi... 详细信息
