Taschenbuch. Zustand: Neu. Neuware -Research issues in Image compression The last decade has been witnessing tremendous and explosive growth in Internet, Mobile communication, and increasing importance of Video communication. Data compression is one of the enabling technologies for each of these aspects of multimedia revolution. As one of the enabling technologies of the multimedia revolution, data compression is a key to rapid progress being made in information technology. It would not be practical to put images, audio, and video without compression. Joint Photographic Experts Group (JPEG) and Moving Pictures Experts Group (MPEG) are standards for representing images and video. Already many researches have taken place in Image compression with the use of wavelets. Still there is a demand for better compression with the use of wavelet variants. This book therefore aims at the research issues related to the usage of Wavelet variants like Multiwavelets, Waveletfootprints, and Contourlets for better image compression.Books on Demand GmbH, Überseering 33, 22297 Hamburg 188 pp. Englisch.

Buch. Zustand: Neu. Neuware -Cryptography has crept into everything, from Web browsers and e-mail programs to cell phones, bank cards, and cars. Shortly, we will see many new exciting applications for cryptography such as radio frequency identification (RFID) tags for anti-counterfeiting. As a consequence of the pervasiveness of crypto algorithms, an increasing number of people must understand how they work and how they can be applied in practice. This book addresses this issue by providing a comprehensive introduction to modern applied cryptography that is equally suited for students and practitioners in industry. Much of the focus is on practical relevance by introducing most crypto algorithms that are used in modern real-world applications. In addition to crypto algorithms, attention is also given to important cryptographic protocols, modes of operation, security services, and key establishment techniques. Timely topics include lightweight ciphers, which are optimized for constrained applications. In today¿s fast-paced world, security and convenience are paramount. Biometrics, the science of identifying individuals based on their unique physical or behavioral traits, offers a solution that is both secure and convenient. From fingerprint scanners on smartphones to facial recognition software at airports, biometrics is rapidly becoming an integral part of our daily lives. But what exactly is biometrics, and how does it work This book delves into the fascinating world of biometrics, exploring its history, applications, and the latest technological advancements. Yoüll discover how biometrics can be used to verify identity, control access, and even detect fraud. Whether yoüre a security professional, a technology enthusiast, or simply curious about the future of personal identification, this book is for you.Books on Demand GmbH, Überseering 33, 22297 Hamburg 204 pp. Englisch.
