  • Deng, Cheng; Gao, Xinbo; Tao, Dacheng; Li, Xuelong (IEEE, 2007)
    In this paper, we present a robust approach of digital watermarking embedding and retrieval for digital images. This new approach works in special domain and it has two major steps: (1) to extract affine co-variant regions, ...
  • Deng, Cheng; Gao, Xinbo; Tao, Dacheng; Li, Xuelong (IEEE, 2008)
    In this paper, we present a robust approach to digital watermarking embedding and retrieval for digital images. The affine-invariant point detector is used to extract feature regions of the given host image. Image normalization ...
  • Gao, Xinbo; Deng, Cheng; Li, Xuelong; Tao, Dacheng (IEEE-Inst Electrical Electronics Engineers Inc, 2010)
    Feature-based image watermarking schemes, which aim to survive various geometric distortions, have attracted great attention in recent years. Existing schemes have shown robustness against rotation, scaling, and translation, ...
  • Deng, Cheng; Gao, Xinbo; Li, Xuelong; Tao, Dacheng (IEEE Computer Soc, 2008)
    In this paper, a robust image watermarking approach is presented based on image local invariant features. The affine invariant point detector is used to extract feature regions of the given host image. Image normalization ...
  • Gao, Xinbo; Deng, Cheng; Li, Xuelong; Tao, Dacheng (Springer, 2010)
    Watermarking aims to hide particular information into some carrier but does not change the visual cognition of the carrier itself. Local features are good candidates to address the watermark synchronization error caused ...
  • Deng, Cheng; Gao, Xinbo; Li, Xuelong; Tao, Dacheng (Elsevier Science Bv, 2010)
    Compared with other existing methods, the feature point-based image watermarking schemes can resist to global geometric attacks and local geometric attacks, especially cropping and random bending attacks (RBAs), by binding ...
  • Deng, Cheng; Gao, Xinbo; Li, Xuelong; Tao, Dacheng (Elsevier Science Bv, 2009)
    Protection against geometric distortions and common image processing operations with blind detection becomes a much challenging task in image watermarking. To achieve this, in this paper we propose a content-based watermarking ...
  • Jia, W; Deng, Cheng; Tao, Dacheng; Zhang, D (IEEE, 2008)
    In this paper, we propose a novel approach for palmprint identification, which contains two interesting components. Firstly, we propose the directional representation for appearance based approaches. The new representation ...
  • An, Ll; Gao, Xinbo; Li, Xuelong; Tao, Dacheng; Deng, Cheng; Li, Jie (IEEE-inst Electrical Electronics Engineers Inc, 2012)
    Robust reversible watermarking (RRW) methods are popular in multimedia for protecting copyright, while preserving intactness of host images and providing robustness against unintentional attacks. However, conventional RRW ...
