Издательство Prentice Hall, 2002, -628 pp.In the past decade or so, there have been fascinating developments in multimedia representation and communications. First of all, it has become very clear that all aspects of media are going digital; from representation to transmission, from processing to retrieval, from studio to home. Second, there have been significant advances in digital multimedia compression and communication algorithms, which make it possible to deliver high-quality video at relatively low bit rates in today’s networks. Third, the advancement in VLSI technologies has enabled sophisticated software to be implemented in a cost-effective manner. Last but not least, the establishment of half a dozen international standards by ISO/MPEG and ITU-T laid the common groundwork for different vendors and content providers. At the same time, the explosive growth in wireless and networking technology has profoundly changed the global communications infrastructure. It is the confluence of wireless, multimedia, and networking that will fundamentally change theway people conduct business and communicate with each other. The future computing and communications infrastructure will be empowered by virtually unlimited bandwidth, full connectivity, high mobility, and rich multimedia capability. As multimedia becomes more pervasive, the boundaries between video, graphics, computer vision, multimedia database, and computer networking start to blur, making video processing an exciting field with input from many disciplines. Today, video processing lies at the core of multimedia. Among the many technologies involved, video coding and its standardization are definitely the key enablers of these developments. This book covers the fundamental theory and techniques for digital video processing, with a focus on video coding and communications. It is intended as a textbook for a graduate-level course on video processing, as well as a reference or self-study text for researchers and engineers. In selecting the topics to cover, we have tried to achieve a balance between providing a solid theoretical foundation and presenting complex system issues in real video systems.Video Formation, Perception, and Representation Fourier Analysis of Video Signals and Frequency Response of The Human Visual System Video Sampling Video Sampling Rate Conversion Video Modeling Two-Dimensional Motion Estimation Three-Dimensional Motion Estimation Foundations of Video Coding Waveform-Based Video Coding Content-Dependent Video Coding Scalable Video Coding Stereo and Multiview Sequence Processing Video Compression Standards Error Control in Video Communications Streaming Video Over the Internet and Wireless IP Networks A: Determination of Spatial–Temporal Gradients B: Gradient Descent Methods C: Glossary of Acronyms D: Answers to Selected Problems
