The authors define data compression and its mathematical foundations and include performance measures of how effective a given compression scheme is. Illustrations from the world of file compression (using Huffman coding, a popular compression scheme) escort readers through basic compression methods. The book also introduces other techniques, such as quantization and predictive coding, and explains today's voice-coding standards.
The latter half of the book does an excellent job of explaining popular standards for compressing data, such as the JPEG standard for images and the MPEG-1 and MPEG-2 standards for video compression. (The authors are on top of new developments, such as emerging standards for multimedia video conferencing and video compression.) Useful appendices outline the important algorithms for compression, and an in-depth bibliography lists sources for research in compression. These features make this book a definitive guide for those who need to know the latest in digital compression technology. --Richard V. Dragan
Drawing on their experience in industry, research, and academia, this powerful author team combines their expertise to provide an accessible guide to data compression standards and techniques and their applications. The essential ideas and motivation behind the various compression methods are presented, and insight is provided into the evolution of the standards. Standards-compliant design alternatives are discussed, and some noncompliant designs also are treated.
Covering the fundamental underpinnings of the most widely used compression methods, this book is intended for engineers and computer scientists designing, manufacturing, and implementing compression systems, as well as system integrators, technical managers, and researchers. It provides, in a single source, an overview of the current standards for speech, audio, video, image, fax, and file compression.
