The GIF format uses the LZW compression algorithm, which was patented by Unisys, and publishers of applications that read and write GIF87a and GIF89a images were required to obtain a license and pay ...
Until now, compression algorithms such as the Lempel-Ziv-Welch (LZW) have been implemented in software. This provided acceptable compression performance in many older systems. But with today's ...
A lossless compression algorithm based on the LZW with compression ratios of 50 ? 60%, using 2K of RAM and 80% or more with 8K or 16K.
In a world with finite storage and an infinite need for more storage space, data compression becomes a very necessary problem. Several algorithms for data compression may be more familiar – Huffman ...
