A patent underlying one of the Web's most popular graphics formats is set to expire later this month, raising the question of whether a rival, open-source format, created as a royalty-free alternative ...

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.

Efficient data compression and transmission are crucial in space missions due to restricted resources, such as bandwidth and storage capacity. This requires efficient data-compression methods that ...

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 ...

Images transmitted over the world wide web are an excellent example of why data compression is important. Suppose we need to download a digitized color photograph over a computer's 33.6 kbps modem. If ...

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 ...
