    Orthogonal neighborhood-preserving projection (ONPP) is a recently developed orthogonal linear algorithm for overcoming the out-of-sample problem existing in the well-known manifold learning algorithm, i.e., locally linear ...
  • Du, C; Yang, Jie; Wu, Qiang; Zhang, Tianhao; Wang, H; Chen, L; Wu, Zj (Springer, 2006)
    In this study, we propose three extended fitting methods to the standard ASM(active shape model). Firstly, profiles are extended from ID to 2D; Secondly, profiles of different landmarks are constructed individually; Thirdly, ...
  • Zhang, Tianhao; Li, Xuelong; Tao, Dacheng; Yang, Jie (World Scientific Publ Co Pte Ltd, 2008)
    Manifold learning has been demonstrated as an effective way to represent intrinsic geometrical structure of samples. In this paper, a new manifold learning approach, named Local Coordinates Alignment (LCA), is developed ...
  • Du, Chunhua; Yang, Jie; Wu, Qiang; Zhang, Tianhao; Yu, Shengyang (SPIE-Soc Photoptical Instrumentation Engineers, 2008)
    This letter develops a novel and fast framework called APLPP to tackle the face recognition task by combining locality preserving projections (LPP) with the affinity propagation clustering method. Unlike LPP, which uses ...
  • Zhang, Tianhao; Li, Xuelong; Tao, Dacheng; Yang, Jie (Elsevier Sci Ltd, 2008)
    Multimodal biometric system utilizes two or more individual modalities, e.g., face, gait, and fingerprint, to improve the recognition accuracy of conventional unimodal methods. However, existing multimodal biometric methods ...
  • Zhang, Tianhao; Tao, Dacheng; Li, Xuelong; Yang, Jie (IEEE Computer Soc, 2009)
    Spectral analysis-based dimensionality reduction algorithms are important and have been popularly applied in data mining and computer vision applications. To date many algorithms have been developed, e. g., principal ...
