無損壓縮LZW算法 image compressionlossless compressionLempel-Ziv-Welch (LZW) algorithm由於以往對LZW無損壓縮算法的研究多是基於平穩遍曆的信源這一假設,而實際的信源多為局部平穩,在此情況下,原LZW算法存在的不足在很大程度上限制了其最終壓縮比的提高.據此,提出了採用雙串表自適應更新機製以取代原算法中的單一串...

Abstract:This paper studied a lossless compression algorithm. The algorithm transforms the image data by integer wavelet, achieving lossless compression with coding wavelet sub-band data with set partitioning in hierarchical trees (SPIHT). The limitation of lossless image compression is probed and image ...

In this paper, a novel lossless image compression algorithm using a bit plane slicing and adaptive Huffman with a Lempel-Ziv-Welch (LZW) dictionary is used and the output received from the algorithm will be used as the inputs for the duplication free run-length coding (DFRLC). This idea ...

LZW: The image will becompressedusing the “Lempel-Ziv-Welch” algorithm, a losslesscompressiontechnique. Common crawl GIF became popular because it usedLZWdatacompression, which was more efficient than the run-length encoding that formats such as those used by PCX and MacPaint, and fairly large...
