This book provides an introductory survey of current research in the broad discipline of source coding. Part one is mainly theoretical and provides the background to source coding; part two then discusses extensive examples of source-coding systems for sound signals and images, at all times relating these back to the key theory presented in part one. Key features of the text include a unifying approach to source coding, a systematic introduction and explanation, close relation of theory with applications and extensive examples, illustrations and exercises. An Introduction to Source Coding will be an invaluable textbook for those on university courses and also a valuable reference work for post-graduates and researchers.
