Lempel-Ziv-Welch Compression Using Multiple Dictionaries

Compression of data has been interesting area of analysis in the previous decade as well as the current. Compression algorithms have been implemented and analyzed for various categories of data. When it comes to preserving the originality of compressed data, lossless compression algorithms have priority. One of the sought after lossless compression methodology is the LZW compression algorithm. Many variants of the original LZW algorithm have been proposed and implemented over years. This paper analyses the usage of Multiple Dictionaries in LZW compression.
