Viewpoint Invariant Human Re-identification in Camera Networks Using Pose Priors and Subject-Discriminative Features
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Ziyan Wu,Yang Li,Richard Radke
Issue Date:February 2015
pp. 1
Human re-identification across cameras with non-overlapping fields of view is one of the most important and difficult problems in video surveillance and analysis. However, current algorithms are likely to fail in real-world scenarios for several reasons. F...
 
Analytical Model of Customer Churn Based on Bayesian Network
Found in: 2013 Ninth International Conference on Computational Intelligence and Security (CIS)
By Peng Sun,Xin Guo,Yunpeng Zhang,Ziyan Wu
Issue Date:December 2013
pp. 269-271
A customer churn analytical model based Bayesian network is built for prediction of customer churn. We propose Bayesian Network approaches to predict churn motivation, mining the result in churn characters in order to help decision-making manager formulate...
 
Keeping a Pan-Tilt-Zoom Camera Calibrated
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Ziyan Wu,Richard J. Radke
Issue Date:August 2013
pp. 1994-2007
Pan-tilt-zoom (PTZ) cameras are pervasive in modern surveillance systems. However, we demonstrate that the (pan, tilt) coordinates reported by PTZ cameras become inaccurate after many hours of operation, endangering tracking and 3D localization algorithms ...
 
Research on Data Recording in Seismic PSD Experiment
Found in: 2012 Eighth International Conference on Computational Intelligence and Security (CIS)
By Peng Sun,Xin Guo,Kang Chen,Ziyan Wu
Issue Date:November 2012
pp. 214-218
Civil Experimental System consists of electric-hydraulic servo-controlled machine and the data recorder in which the recorded data are saved. In Electro-hydraulic servo controller, a exterior trigger signal is used to remote control the data recorder worki...
 
Towards Improved Paper-Based Election Technology
Found in: Document Analysis and Recognition, International Conference on
By Elisa H. Barney Smith,Daniel Lopresti,George Nagy,Ziyan Wu
Issue Date:September 2011
pp. 1255-1259
Resources are presented for fostering paper-based election technology. They comprise a diverse collection of real and simulated ballot and survey images, and software tools for ballot synthesis, registration, segmentation, and ground truthing. The grids un...
 
Research on Optimal Sensor Placement Using Effective Two-Step Arrangement Approach
Found in: Intelligent Computation Technology and Automation, International Conference on
By Ziyan Wu, Haifeng Yang, Yunju Yan
Issue Date:October 2009
pp. 458-461
Optimal sensor placement method is very important in structural vibration test. This paper proposes an effective two-step arrangement method for sensors optimization, which is suitable for on-line monitoring scheme. In the first step, we calculate the utmo...
