The Lempel–Ziv–Welch (LZW) algorithm is a lossless data compression algorithm. LZW is an adaptive compression algorithm that does not assume prior knowledge of the input data distribution. This ...

This is an Optimised Notepad which auto-compresses the text-file when the file is saved. Combination of compression Algorithms (LZW compression and Huffman compression algorithms) are used to compress ...

Abstract: The LZW compression is a well known patented lossless compression method used in Unix file compression utility "compress" and in GIF and TIFF image formats. It converts an input string of ...

Abstract: In the paper, a new parallel LZW-Like algorithm, bi-directory LZW algorithm (BD-LZW) will be interpreted. The new algorithm can be used in data compression ...

In this paper, we analyze the complexity and entropy of different methods of data compression algorithms: LZW, Huffman, Fixed-length code (FLC), and Huffman after using Fixed-length code (HFLC). We ...

I hope this little document will help enlighten those of you out there who want to know more about the Lempel-Ziv Welch (LZW) compression algorithm, and, specifically, the implementation that GIF uses ...

ABSTRACT: In this paper, we analyze the complexity and entropy of different methods of data compression algorithms: LZW, Huffman, Fixed-length code (FLC), and Huffman after using Fixed-length code ...
