Data and Image Compression

Addressing a key issue in communications, this study explores how practical data and image compression routines are now vital for the efficient, low-cost transmission of data. The compression-performing programs ARC, ARJ, PKZIP and VC2 are described in detail.

Data and image compression is a key issue in communications. As the computer communications revolution continues to expand, the requirement for data storage and transmission continues to soar. Guiding the reader through the main techniques, this book explains how practical data and image compression routines are now vital for efficient, low-cost transmission. This new edition of "Data Compression" has been restructured to take account of the many new advances in this important field, with major features to include the four most popular archive creation and compression performing programmes - ARC, ARJ, PKZIP and VC2. Operational explanations of over 20 compression algorithms, including the recently developed BPE algorithm, fax compression and description of several dictionary-based string compression algorithms. The accompanying convenience diskettes contain coding in the BASIC and C for a large number of compression algorithms referenced in the book.
