Data Compression

This paper surveys a variety of data compression methods spanning almost forty years of research, from the work of Shannon, Fano and Huffman in the late 40's to a technique developed in 1986. The aim of data compression is to reduce redundancy in stored or communicated data, thus increasing effective data density.

Data-Compression.com

A website devoted to the principles and practice of data compression ... The goal of data compression is to represent an information source (e.g. a data file, a speech signal, an image, or a video signal) as accurately as possible using the fewest number of bits.

Theory of Data Compression

Shannon also developed the theory of lossy data compression. This is better known as rate-distortion theory. In lossy data compression, the decompressed data does not have to be exactly the same as the original data.
