FUNCTIONAL PEARLS Inverting the Burrows-Wheeler Transform
نویسنده
چکیده
Our aim in this pearl is to exploit simple equational reasoning to derive the inverse of the Burrows-Wheeler transform from its specification. We also outline how to derive the inverse of two more general versions of the transform, one proposed by Schindler and the other by Chapin and Tate.

Burrows-Wheeler transformations and de Bruijn words
We formulate and explain the extended Burrows–Wheeler transform ofMantaci et al. from the viewpoint of permutations on a chain taken as a union of partial order-preserving mappings. In so doing we establish a link with syntactic semigroups of languages that are themselves cyclic semigroups.We apply the extended transformwith a view to generating de Bruijn words through inverting the transform. ...

The objective of this pearl is to derive the inverse of the Burrows-Wheeler transform from its specification, using simple equational reasoning. In fact, we derive the inverse of a more general version of the transform, proposed by Schindler.
متن کاملOutput distribution of the Burrows - Wheeler transform ' Karthik
The Burrows-Wheeler transform is a block-sorting algorithm which has been shown empirically to be useful in compressing text data. In this paper we study the output distribution of the transform for i.i.d. sources, tree sources and stationary ergodic sources. We can also give analytic bounds on the performance of some universal compression schemes which use the Burrows-Wheeler transform.
متن کاملImprovements to the Burrows-Wheeler Compression Algorithm: After BWT Stages
The lossless Burrows-Wheeler Compression Algorithm has received considerable attention over recent years for both its simplicity and effectiveness. It is based on a permutation of the input sequence − the Burrows-Wheeler Transform − which groups symbols with a similar context close together. In the original version, this permutation was followed by a Move-To-Front transformation and a final ent...
متن کاملAttacking Scrambled Burrows-Wheeler Transform
Scrambled Burrows-Wheeler transform [6] is an attempt to combine privacy (encryption) and data compression. We show that the proposed approach is insecure. We present chosen plaintext and known plaintext attacks and estimate their complexity in various scenarios.
