Your project is analyzing and enhancement of the selected paper along with implementation of enhanced version of it. Dr. A. Fathi, Data Compression 3 Razi University Basic Concepts in the Information Theory Data Compression Razi University Data compression, in the context of computer science, is the science (and art) of representing information in a compact form to: Conserve storage space Reduce time for transmission Faster to encode, send, then decode than to send the original Progressive transmission Some compression techniques allow us to send the most important bits first so we can get a low resolution version of some data before getting the high fidelity version Reduce computation Use less data to achieve an approximate answer Dr. A. Fathi, Data Compression 5 What is Data and Information Razi University Data and information are not synonymous terms! Data is the means by which information is conveyed.
