This book was released on 2012-07 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing problem of the unauthorized reproduction of digital multimedia data such as movies, television broadcasts, and similar digital products has triggered worldwide efforts to identify and protect multimedia contents. Watermarking refers to the process of adding a structure called a watermark to an original data object. Such a watermark can be used for several purposes including copyright protection, fingerprinting, copy protection, broadcast monitoring, data authentication, indexing, and medical safety. This book presented robust watermarking algorithms for 2D images, 3D models, and video image sequences. We have demonstrated the use of these algorithms in multimedia copyright protection. The objective was to embed information about the owner of the data in order to prevent other parties from claiming the copyright on that data. We have verified the effectiveness of the proposed methods through experimental results with a variety of 2D images, 3D models, and video image sequences. We have achieved the balance between the imperceptibility of the watermarked multimedia document and its robustness against intentional and geometric attacks.

Book excerpt: The growing problem of the unauthorized reproduction of digital multimedia data such as movies, television broadcasts, and similar digital products has triggered worldwide efforts to identify and protect multimedia contents. Digital watermarking technology provides law enforcement officials with a forensic tool for tracing and catching pirates. Watermarking refers to the process of adding a structure called a watermark to an original data object, which includes digital images, video, audio, maps, text messages, and 3D graphics. Such a watermark can be used for several purposes including copyright protection, fingerprinting, copy protection, broadcast monitoring, data authentication, indexing, and medical safety. The proposed thesis addresses the problem of multimedia protection and consists of three parts. In the first part, we propose new image watermarking algorithms that are robust against a wide range of intentional and geometric attacks, flexible in data embedding, and computationally fast. The core idea behind our proposed watermarking schemes is to use transforms that have different properties which can effectively match various aspects of the signal's frequencies. We embed the watermark many times in all the frequencies to provide better robustness against attacks and increase the difficulty of destroying the watermark. The second part of the thesis is devoted to a joint exploitation of the geometry and topology of 3D objects and its subsequent application to 3D watermarking. The key idea consists of capturing the geometric structure of a 3D mesh in the spectral domain by computing the eigen-decomposition of the mesh Laplacian matrix. We also use the fact that the global shape features of a 3D model may be reconstructed using small low-frequency spectral coefficients. The eigen-analysis of the mesh Laplacian matrix is, however, prohibitively expensive. To lift this limitation, we first partition the 3D mesh into smaller 3D sub-meshes, and then we repeat the watermark embedding process as much as possible in the spectral coefficients of the compressed 3D sub-meshes. The visual error of the watermarked 3D model is evaluated by computing a nonlinear visual error metric between the original 3D model and the watermarked model obtained by our proposed algorithm. The third part of the thesis is devoted to video watermarking. We propose robust, hybrid scene-based MPEG video watermarking techniques based on a high-order tensor singular value decomposition of the video image sequences. The key idea behind our approaches is to use the scene change analysis to embed the watermark repeatedly in a fixed number of the intra-frames. These intra-frames are represented as 3D tensors with two dimensions in space and one dimension in time. We embed the watermark information in the singular values of these high-order tensors, which have good stability and represent the video properties. Illustration of numerical experiments with synthetic and real data are provided to demonstrate the potential and the much improved performance of the proposed algorithms in multimedia watermarking.

Available in PDF, EPUB and Kindle. Book excerpt: Digital audio, video, images, and documents are flying through cyberspace to their respective owners. Unfortunately, along the way, individuals may choose to intervene and take this content for themselves. Digital watermarking and steganography technology greatly reduces the instances of this by limiting or eliminating the ability of third parties to decipher the content that he has taken. The many techiniques of digital watermarking (embedding a code) and steganography (hiding information) continue to evolve as applications that necessitate them do the same. The authors of this second edition provide an update on the framework for applying these techniques that they provided researchers and professionals in the first well-received edition. Steganography and steganalysis (the art of detecting hidden information) have been added to a robust treatment of digital watermarking, as many in each field research and deal with the other. New material includes watermarking with side information, QIM, and dirty-paper codes. The revision and inclusion of new material by these influential authors has created a must-own book for anyone in this profession. - This new edition now contains essential information on steganalysis and steganography - New concepts and new applications including QIM introduced - Digital watermark embedding is given a complete update with new processes and applications

Download or read book Robust Watermarking Schemes for Multimedia Protection written by Mohamed Ouhsain and published by . This book was released on 2007 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid growth of digital multimedia data and the increasing use of the World Wide Web have triggered the need for the protection of multimedia contents (images, 3D graphics, audio, video). Digital watermarking has been proposed as an effective solution to the multimedia protection. The great challenge, however, is to devise efficient and robust watermarking schemes to tackle the fundamental tradeoff between robustness, data payload, and imperceptibility. This thesis is devoted to two robust watermarking schemes that we have developed for copyright protection. The first watermarking scheme uses discrete wavelet transform (DWT) and nonnegative matrix factorization (NMF). The core idea consists of decomposing an image into four wavelet sub-bands and then applying NMF to the blocks of each sub-band, followed by an eigen-decomposition distortion step. The second watermarking scheme uses multiple parameter discrete fractional Fourier (MPDFRF) transform and DWT. The original cover image is decomposed into four wavelet sub-bands, followed by a segmentation of each sub-band into blocks. Then the MPDFRF transform is applied to each block. The rest of the thesis is devoted to 3D mesh compression and fingerprinting. We propose a mesh compression technique using the mesh umbrella matrix. The key idea is to apply eigendecomposition to the umbrella matrix, and then retain the eigenvalues and eigenvectors which contain the low frequency coefficients. We also propose a mesh fingerprinting method by partitioning a 3D mesh into sub-meshes to produce the fingerprint vectors for all the sub-meshes.
