By Zhijie Xu,Shiliang Sun
Issue Date:November 2011
pp. 399-402
Transfer learning, serving as one of the most important research directions in machine learning, has been studied in various fields in recent years. In this paper, we integrate the theory of multi-view learning into transfer learning and propose a new algo...
Boosting for Learning a Similarity Measure in 2DPCA Based Face Recognition
Found in: Computer Science and Information Engineering, World Congress on
By Zhijie Xu, Jianqin Zhang, Xiwu Dai
Issue Date:April 2009
pp. 130-134
In this paper we address the problem of identifying the similarity measure for face recognition. The similarity measure plays an important role in pattern classification. However, with reference to 2D image matrix based methods for face recognition, such a...
GPGPU-based Gaussian Filtering for Surface Metrological Data Processing
Found in: Information Visualisation, International Conference on
By Yang Su, Zhijie Xu, Xiangqian Jiang
Issue Date:July 2008
pp. 94-99
Engineering surfaces are characterized by the form, waviness and roughness features that are comprised of a range of spatial wavelengths. Filtering techniques are commonly adopted to separate these different wavelength components into well-defined bandwidt...

Using Motion Platform as a Haptic Display for Virtual Inertia Simulation
Found in: Information Visualisation, International Conference on
By Zhijie Xu, Dave Taylor
Issue Date:July 2003
pp. 498
Haptic displays serve great importance in creating the immersiveness sense that block Virtual Reality (VR) users from the contradictory impressions from the real world. This paper introduces the general structure of Virtual Reality systems. It reports comm...
Illuminant Condition Matching in Augmented Reality: A Multi-Vision, Interest Point Based Approach
Found in: Computer Graphics, Imaging and Visualization, International Conference on
By Mark Bingham, Dave Taylor, Zhijie Xu, Duke Gledhill
Issue Date:August 2009
pp. 57-61
For the output of an augmented reality application to appear realistic a number of issues need to be taken into consideration. The illumination correspondence between the real and virtual components should be taken into account as well as the scene level o...
