Synopses & Reviews
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 and data storage requirements. Building on the success of the third edition of Data Compression the scope of the fourth edition has been restructured to take account of the many new advances in this important field. Major features include:
* A review of the four most popular archive creation and compression performing programs - ARC, ARJ, PKZIP and UC2
* Operational explanation of over 20 compression algorithms including the recently developed BPE algorithm
* Fax compression and methods
* Description of several dictionary-based string compression algorithms and respective advantages and disadvantages
* Learning and operating compression-related tools to display, print and convert images from one format to another
The accompanying convenience diskettes contain the coding in Basic and C for a large number of compression algorithms referenced within the book. Each of these programs and several shareware programs can be used to facilitate reduction in file storage and time required to transmit files between computers.
Synopsis
Now covering both data and image compression, this edition keeps pace with technology. It includes new coverage of fax and compression methods, as well as a range of compression-related tools to display, print, and convert images from one format to another. Reviews of the four most popular archive creation and compression performing programs are also included. Two disks include the coding in BASIC and C for many of the compression algorithms in the book.
