Издательство Academic Press, 2002, -317 pp.Motivated by the vision of being able to communicate from anywhere at any time with any type of information, a natural convergence of mobile and multimedia is under way. This new area, called mobile multimedia communications, is expected to achieve unprecedented growth and worldwide commercial success. Current second-generation mobile communication systems support a number of basic multimedia communication services. However, many technologically demanding problems need to be solved before real-time mobile video communications can be achieved. When such challenges are resolved, a wealth of advanced services and applications will be available to the mobile user. This book concentrates on three main challenges: 1. Higher coding efficiency 2. Reduced computational complexity 3. Improved error resilience Mobile video communications is an interdisciplinary subject. Complete systems are likely to draw together solutions from different areas, such as video source coding, channel coding, network design, and semiconductor design, among others. This book concentrates on solutions based on video source coding. In this context, the book adopts a motion-based approach, where advanced motion estimation techniques, reduced-complexity motion estimation techniques, and motion-compensated error concealment techniques are used as possible solutions to the three challenges, respectively. The idea of this book originated in 1997, when the first author was in the early stages of his Ph.D. studies. As a newcomer to the field, he started consulting a number of books to introduce himself to the fundamentals and standards of video source coding. He realized, however, that, for a beginner, most of these books seemed too long and too theoretical, with no treatment of some important practical and implementation issues. As he progressed further in his studies, the first author also realized that the areas of coding efficiency, computational complexity, and error resilience are usually treated separately. Thus, he always wished there was a book that provided a quick, easy, and practical introduction to the fundamentals and standards of video source coding and that brought together the areas of coding efficiency, computational complexity, and error resilience in a single volume. This is exactly the purpose of this book.Introduction to Mobile Video Communications Introduction to Video Coding Video Coding: Fundamentals Video Coding: Standards Coding Efficiency Basic Motion Estimation Techniques Warping-Based Motion Estimation Techniques Multiple-Reference Motion Estimation Techniques Computational Complexity Reduced-Complexity Motion Estimation Techniques The Simplex Minimization Search Error Resilience Error-Resilience Video Coding Techniques Error Concealment Using Motion Field Interpolation Appendix Fast Block-Matching Algorithms
