Although this is a simple approach, there are two major obstacles that need to be overcome: (1) how to determine what sequences should be in the code table, and (2) how to provide the uncompression ...

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.

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.

Unisys attracted criticism when it said that Web sites that provide GIFs for download that were created with an unlicensed copy of the Lempel-Ziv-Wlech (LZW) compression algorithm were guilty of ...

Hi,I'm working on a LZW compression assignment in Java. For compression, I start with the initial dictionary of all the ascii characters so 0 - 255 are stored as codes.However, once I get repeated ...

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 ...

Google is no Silicon Valley startup, but it's just as intent on creating compression algorithms as the fictional "Pied Piper." The search giant is about to unleash its latest algorithm, called ...

Everyone has unzipped files via an algorithm called Deflate that has been used for data compression for 20 years. Now Facebook says it has something better called Zstandard.
