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.

The effects of digital technology on the security industry require constant vigilance by security distributors, sales staff, and installation professionals. Today and for the foreseeable future, all security professionals must have at least a basic understanding of digital technology. Digital CCTV addresses this new challenge. Topics convered include compression variables such as Lossless and Lossy, which are explained by reviewing Huffman and Run Length Encoding (RLE), and by relating these forms of compression to ZIP and Stuffit, which are commonly used in personal computers. A review of JPEG, motion JPEG, MPEG and wavelet compression schemes among others, with a comparison of the merits of each, is also provided. As Digital CCTV traces the stream of digital video flow from the computer industry through compression, transmission, display and storage, and explains how analog video signal is converted into a digital signal, the reader will learn and understand the mysteries of digital science.

Media and the American Child summarizes the research on all forms of media on children, looking at how much time they spend with media everyday, television programming and its impact on children, how advertising has changed to appeal directly to children and the effects on children and the consumer behavior of parents, the relationship between media use and scholastic achievement, the influence of violence in media on anti-social behavior, and the role of media in influencing attitudes on body image, sex and work roles, fashion, & lifestyle. The average American child, aged 2-17, watches 25 hours of TV per week, plays 1 hr per day of video or computer games, and spends an additional 36 min per day on the internet. 19% of children watch more than 35 hrs per week of TV. This in the face of research that shows TV watching beyond 10 hours per week decreases scholastic performance. In 1991, George Comstock published Television and the American Child, which immediately became THE standard reference for the research community of the effects of television on children. Since then, interest in the topic has mushroomed, as the availability and access of media to children has become more widespread and occurs earlier in their lifetimes. No longer restricted to television, media impacts children through the internet, computer and video games, as well as television and the movies. There are videos designed for infants, claiming to improve cognitive development, television programs aimed for younger and younger children-even pre-literates, computer programs aimed for toddlers, and increasingly graphic, interactive violent computer games.

Visualization in Medicine is the first book on visualization and its application to problems in medical diagnosis, education, and treatment. The book describes the algorithms, the applications and their validation (how reliable are the results?), and the clinical evaluation of the applications (are the techniques useful?). It discusses visualization techniques from research literature as well as the compromises required to solve practical clinical problems. The book covers image acquisition, image analysis, and interaction techniques designed to explore and analyze the data. The final chapter shows how visualization is used for planning liver surgery, one of the most demanding surgical disciplines. The book is based on several years of the authors' teaching and research experience. Both authors have initiated and lead a variety of interdisciplinary projects involving computer scientists and medical doctors, primarily radiologists and surgeons.

"Lois Alba is a master teacher, ...I have never seen a vocal instructor who got such remarkable results in such a short time." - Irene Dalis, General Director, Opera San Jose Achieving a successful singing career, especially in opera, can seem almost impossible to many singers because of fear of high notes, lack of projection, and confusion on how to express the music unhampered by technical preoccupation. Master Teacher and accomplished opera singer Lois Alba is aware of these pitfalls. She knows the best teaching involves an acute sense of the art form based on sound, intuition and imagery. The focus comes from the mind. It is interpreted through the ear and the body. When the body and mind come together harmoniously the result is beautiful sound. In this clear and legible guide, Lois Alba shares her formidable experience, voice training insight, and philosophical wisdom about the creative nature of singing. She works to de-program the singer as to the many myths about singing û recurring themes that flood vocal studios and ultimately damage voices. Vocal Rescue is an amalgamation of many precepts from a large library of rare treatises and the concepts outlined come from the fine art of vocal mastery known as bel canto. The text provides a seven step system that demystifies the secrets to beautiful singing, and promises to take all singers to a new level of technical proficiency and expression. Recorded illustrations on CD/DVD demonstrate the vocal principles with lessons and vocalises for singers in all voice ranges to follow. The author's website can be found at www.loisalba.com

Rendering is a crucial component of computer graphics— the conversion of a description of a 3D scene into an image for display. Algorithms for animation, geometric modeling, and texturing all must feed their results through some sort of rendering process for the results to be visible in an image. Focusing on realistic images, physically based rendering incorporates ideas from a range of disciplines, including physics, biology, psychology, cognitive science, and mathematics. This book presents the algorithms of modern photorealistic rendering and follows step by step the creation of a complete rendering system. As each new rendering concept is introduced it is also shown implemented in code—there is no better way to understand the subtle and complex process of rendering. The code itself is highly readable, written in the literate programming style that mixes text describing the system with the code that implements it. The result is a stunning achievement in graphics education for students, professionals, and researchers.
