LZW Data Compression Lempel”Ziv”Welch (LZW) is a lossless data compression technique that was created back in 1984 by Terry Welsh as an improvement to the popular LZ77 compression algorithm.

[Part 2 examines delta encoding and LZW compression.] Data transmission and storage cost money. The more information being dealt with, the more it costs. In spite of this, most digital data are not ...

Coding, information theory and compression constitute the backbone of modern digital communications and data storage. Grounded in Shannon’s seminal work, information theory quantifies the ...

ADCs and DACs are generating a flood of sampled data that are creating high-speed bottlenecks on busses and in networks. Part 1 of this article described the use of compression algorithms that take ...

Several algorithms for data compression may be more familiar – Huffman coding, LZW compression – and some a bit more arcane.

GENEVA, Switzerland—A new group tasked with using artificial intelligence to improve the efficiency of data compression was announced here on Sept 30. Several forces were behind the establishment of ...
