Book Description
Video watermarking technology enables us to hide an imperceptible, robust, and secure data in digital or analog video. This data can be used for tracking, fingerprinting, copyright infringement detection or any other application that requires some hidden data. Video watermarking can be achieved by either applying still image technologies to each frame of the movie or by using dedicated methods which exploit inherent features of the video sequence. There is a complex trade-off between three requirements in digital watermarking: robustness against noise and attacks, imperceptibility or invisibility, and capacity, which represent the amount of data, i.e., the number of bits encoded by the watermark. However, these three requirements conflict with each other. Increasing the watermark strength makes the system more robust but unfortunately decreases the perceptual quality. Whereas, increasing the capacity of the watermark decreases the robustness.In the production chain, video compression is usually applied before broadcasting or before transferring the video to other devices. In order to be robust against format conversions, the watermark has to be inserted before compression. Therefore, uncompressed video format has been used in the research undertaken. On the other hand, a random key is used to choose the frames to be watermarked to increase the security level of the algorithm and discourage piracy. The aim of this research is to develop a video watermarking algorithm to embed a binary image inside the uncoded video stream that acts as a logo. A mid-band discrete wavelet transform coefficients of the selected frames are chosen to be the hosted region in the frequency domain. An inverse transformation should be taken in order to get the desired watermarked video shot. In extraction process the watermark is extracted from the marked video directly without access to the original video. The experiment results showed that the proposed scheme provides better quality watermarked videos in term of watermark invisibility to human eyes. Results also indicated that obtaining average peak signal to noise ratio (PSNR) equals 41.59dB as compared with 38.48dB in the case of direct embedding. In addition, the scheme is robust against video processing operations, such as MPEG compression which could be successfully recovered. In conclusion, modifying the wavelet coefficients depending only on the logo object's pixels highly improve the invisibility and at the same time providing a good robustness level.

Book Description
Welcome to the second IEEE Pacific Rim Conference on Multimedia (IEEE PCM 2001) held in Zhongguanchun, Beijing, China, October 22 24, 2001. Building upon the success of the inaugural IEEE PCM 2000 in Sydney in December 2000, the second PCM again brought together the researchers, developers, practitioners, and educators of multimedia in the Pacific area. Theoretical breakthroughs and practical systems were presented at this conference, thanks to the sponsorship by the IEEE Circuit and Systems Society, IEEE Signal Processing Society, China Computer Foundation, China Society of Image and Graphics, National Natural Science Foundation of China, Tsinghua University, and Microsoft Research, China. IEEE PCM 2001 featured a comprehensive program including keynote talks, regular paper presentations, posters, demos, and special sessions. We received 244 papers and accepted only 104 of them as regular papers, and 53 as poster papers. Our special session chairs, Shin'ichi Satoh and Mohan Kankanhalli, organized 6 special sessions. We acknowledge the great contribution from our program committee members and paper reviewers who spent many hours reviewing submitted papers and providing valuable comments for the authors. The conference would not have been successful without the help of so many people. We greatly appreciated the support of our honorary chairs: Prof. Sun Yuan Kung of Princeton University, Dr. Ya Qin Zhang of Microsoft Research China, and Prof.

Book Description
The past decade has seen a rapid growth in the demand for biometric-based - thentication solutions for a number of applications. With signi?cant advances in biometrictechnologyandanincreaseinthenumberofapplicationsincorporating biometrics, it is essential that we bring together researchers from academia and industry as well as practitioners to share ideas, problems and solutions for the development and successful deployment of state-of-the-art biometric systems. The InternationalConference onBiometric Authentication (ICBA 2004)was the?rst major gathering in the Asia-Paci?c region devoted to facilitating this interaction. We are pleased that this conference attracted a large number of high-quality research papers that will bene?t the international biometrics - search community. After a careful review of 157 submissions, 101 papers were acceptedeitherasoral(35)orposter(66)presentations. Inadditiontothesete- nical presentations, this conference also presented the results and summaries of threebiometric competitions: FingerprintVeri?cationCompetition (FVC 2004), Face Authentication Competition (FAC 2004), and Signature Veri?cation C- petition (SVC 2004). This conference provided a forum for the practitioners to discuss their practical experiences in applying the state-of-the-art biometric technologies which will further stimulate research in biometrics. We aregrateful to Jim L. Wayman, Edwin Rood, Raymond Wong, Jonathon Philips, andFrancisHoforacceptingourinvitationtogivekeynotetalksatICBA 2004.

Book Description
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
