imageImage and video compression standards : algorithms and architectures / Vasudev Bhaskaran, Konstantinos Konstantinides. – 2. ed. – Boston [etc.] : Kluwer Academic, c1997. – XVI, 454 p. ; 24 cm.

Collocazione: 22m/0646

Image and Video Compression Standards: Algorithms and Architectures, Second Edition presents an introduction to thealgorithms and architectures that form the underpinnings of the imageand video compressions standards, including JPEG (compression ofstill-images), H.261 and H.263 (video teleconferencing), and MPEG-1and MPEG-2 (video storage and broadcasting). The next generation ofaudiovisual coding standards, such as MPEG-4 and MPEG-7, are alsobriefly described. In addition, the book covers the MPEG and DolbyAC-3 audio coding standards and emerging techniques for image andvideo compression, such as those based on wavelets and vectorquantization.

Image and Video Compression Standards: Algorithms andArchitectures, Second Edition emphasizes the foundations ofthese standards; namely, techniques such as predictive coding,transform-based coding such as the discrete cosine transform (DCT),motion estimation, motion compensation, and entropy coding, as well ashow they are applied in the standards. The implementation details ofeach standard are avoided; however, the book provides all the materialnecessary to understand the workings of each of the compressionstandards, including information that can be used by the reader toevaluate the efficiency of various software and hardwareimplementations conforming to these standards. Particular emphasis isplaced on those algorithms and architectures that have been found tobe useful in practical software or hardware implementations.

Image and Video Compression Standards: Algorithms andArchitectures, Second Edition uniquely covers all majorstandards (JPEG, MPEG-1, MPEG-2, MPEG-4, H.261, H.263) in asimple andtutorial manner, while fully addressing the architecturalconsiderations involved when implementing these standards. As such, itserves as a valuable reference for the graduate student, researcher orengineer. The book is also used frequently as a text for courses onthe subject, in both academic and professional settings.
