  • Content Protection for MPEG-4 Video with Watermarking

    Publication Year: 2006, Page(s):1 - 5
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4724 KB) | HTML iconHTML

    This paper presents a MPEG-4 video codec based watermarking scheme to protect video content. This scheme provides dual protection for intellectual property rights (IPR), utilizing error propagation in temporal MCP. Watermark is embedded into I-VOP, and is adjusted before I-VOP is reconstructed as reference VOP. During decoding, the embedded watermark in I-VOP is adjusted by the same way as in enco...

    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4145 KB) | HTML iconHTML

    A novel digital image watermarking scheme is proposed, which is based on Walsh spread spectrum for watermark embedding in DWT domain. Our main contributions are below: 1) texture regions have been chosen to embed the watermark information and a simple texture region detection method is presented; 2) the auxiliary information is introduced to locate the watermark region during extracting process, w...

    Imperceptibility, robustness and hiding rate are the three most important indexes of digital watermarking. They restrict each other. In this paper, we firstly give a digital watermarking model and the definitions of the three indexes. Based on them, the quantificational relation of the three indexes is gained. Then we point out that the embedding intensity is the key to reach their tradeoffs and p... View full abstract»

  • Digital Watermarking of Spectral Images Using DWT-SVD

    Publication Year: 2006, Page(s):15 - 18
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3382 KB) | HTML iconHTML

    A watermarking method based on discrete wavelet transform (DWT) and singular value decomposition (SVD) is presented for spectral images. After decomposing the spectral image with three-dimensional wavelet transform, we apply the SVD to each band of transformed spectral image, and embed the watermark by modifying the singular value. After modification the image is reconstructed, thus containing the... View full abstract»

  • Low Luminance Smooth Blocks Based Watermarking Scheme in DCT Domain

    Publication Year: 2006, Page(s):19 - 23
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5241 KB) | HTML iconHTML

    In this paper, we present a new watermarking algorithm based on low luminance smooth blocks in compressed DCT domain. The blocks are selected by sorting the 8times8 DCT blocks according to the value of DC coefficients and the variance of AC coefficients respectively. The watermark is embedded in these blocks, in which the value of DC and variance of the AC are both small. This scheme depends on sh... View full abstract»

  • A New Geometric-Transformation Robust and Practical Embedding Scheme for Watermarking 2D Vector Maps in the Graph Spectral Domain

    Publication Year: 2006, Page(s):24 - 30
    Cited by:  Papers (5)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (6934 KB) | HTML iconHTML

    In this paper, we first analyze the geometric-transformation robustness and computing performance of the previous watermarking algorithms for vector maps in the graph spectral domain, and propose that translation of a vector map affects only the first graph spectral coefficient, the watermarks embedded in the graph spectral coefficients can't remain invariant to scaling and rotation. In succession... View full abstract»

  • Iris Feature Extraction Based on Wavelet Packet Analysis

    Feature extraction is the crucial part of an iris recognition system. Multi-resolution analysis such as Gabor filters and wavelet transform (WT) help to characterize different scales of iris texture. In this paper, we propose a novel multi-resolution approach based on wavelet packets transform (WPT) for iris texture analysis and recognition. The development of this approach is motivated by the obs... View full abstract»
