An Intelligent LZWS Compression Algorithm to Achieve High Compression by Using an Efficient Technique (original) (raw)

International journal of innovative research and development, 2013

Abstract

Data compression is a key component for data storage systems and for communication purposes. Lempel-Ziv-Welch (LZW) data compression algorithm is popular for data compression because it is an adaptive algorithm and achieves an excellent compromise between compression performance and speed of execution. LZW is a dictionary based data compression algorithm, which compress the data in a lossless manner so that no information is lost. But LZW algorithm fails in case of small amount of data. In this case it expands the data instead of compressing it. In this paper a system is proposed to achieve high compression even if data file contains small amount of data.
