In [16], the authors proposed a method that combined word with LZW First, their method splits input text to word and nonword and then uses them as initial alphabet of LZW Reference [17] proposed a technique to compress short text messages based on two phases.
Three typical data compression methods are considered: the lossless weighted LZW coding [17], lossy JPEG [18], and MPEG audio coding layer 1 [19].
TIFF LZW works best when practical to monochrome or 8-bit grayscale or LUT
Huffman and LZW algorithms are respectively typical examples of these two classes.
Resolucion 400 dpi, compresion LZW, 4 bits, escala de grises.
Admite varias formas de compresion con perdida de informacion o sin ella, como JPEG y LZW respectivamente.
Grayscale digital pictures (TIFF-format, 300 dpi resolution, no LZW compression) of the leaves were scanned on a 1-mm gridded background and contrast-enhanced (60%) in Adobe Photoshop v.
Nearly as useful is the TIFF format, which can be saved either uncompressed or with the lossless LZW compression method.
A more powerful version of HE is called LZW compression after its developers Abraham Lempel, Jacob Ziv and Terry Welch.
El algoritmo LZW es un refinamiento popular de LZ78, permitiendo palabras codigo de tamano variable cancelando antiguas cadenas del diccionario, como lo implementado en el algoritmo GIF (formato de intercambio grafico).
