Burrows Wheeler Transformation
Youtube The Burrows-Wheeler Transform: A Powerful Tool for Data Compression Introduction The Burrows-Wheeler transform (BWT) is a data transformation algorithm that restructures data in such a way that the transformed message is more suitable for compression. The BWT is used in a variety of data compression algorithms, including bzip2 and Burrows-Wheeler block-sorting compression (bzip). The BWT was invented by Michael Burrows and David Wheeler in 1994. It is based on the idea of permuting the characters of a string T into another string BWTT. The permutation is constructed in such a way that the transformed message is more compressible than the original message. The BWT has a number of advantages over other data compression algorithms. First, the BWT is very efficient. It can be computed in linear time and space. Second, the BWT is lossless, meaning that no information is lost during the compression process. Third, the BWT is invertible, meaning that the orig...
