Burrows-Wheeler based JPEG
Recently, the use of the Burrows-Wheeler method for data compression has been expanded. A method of enhancing the compression efficiency of the common JPEG standard is presented in this paper, exploiting the Burrows-Wheeler compression technique. The paper suggests a replacement of the traditional Huffman compression used by JPEG by the Burrows-Wheeler compression. When using high quality image...
متن کاملSyllable-Based Burrows-Wheeler Transform
The Burrows-Wheeler Transform (BWT) is a compression method which reorders an input string into the form, which is preferable to another compression. Usually Move-To-Front transform and then Huffman coding is used to the permutated string. The original method [3] from 1994 was designed for an alphabet compression. In 2001, versions working with word and n-grams alphabet were presented. The newe...
متن کاملBurrows Wheeler Compression
Author’s Note. The material of this chapter, while quoting extensively from other work, is in part a summary of my own experience and thoughts in working with the Burrows-Wheeler compression algorithm. Some of it is accordingly rather less formal in style than might otherwise be the case, as I give more personal opinions on various aspects. Where my own work already appears in the public domain...
متن کاملThe Burrows-Wheeler Algorithm
The Burrows-Wheeler Algorithm was published in the year 1994 by Michael Burrows and David Wheeler in the research report “A Block-sorting Lossless Data Compression Algorithm”. This research report is based on an unpublished work by David Wheeler from the year 1983. The Burrows-Wheeler Algorithm will used for data compression. The algorithm consists of several stages and these stages are perform...
متن کاملDynamic Burrows-Wheeler Transform
The Burrows-Wheeler Transform is a building block for many text compression applications and self-index data structures. It reorders the letters of a text T to obtain a new text bwt(T ) which can be better compressed. This forward transform has been intensively studied over the years, but a major problem still remains: bwt(T ) has to be entirely recomputed whenever T is modified. In this articl...
