A Bijective String Sorting Transform
Given a string of characters, the Burrows-Wheeler Transform rearranges the characters in it so as to produce another string of the same length which is more amenable to compressio...

RadixZip: Linear-Time Compression of Token Streams
RadixZip is a block compression technique for token streams. It introduces RadixZip Transform, a linear time algorithm that rearranges bytes using a technique inspired by radix so...

Move-to-Front, Distance Coding, and Inversion Frequencies Revisited
Move-to-Front, Distance Coding and Inversion Frequencies are three simple and effective techniques used to process the output of the Burrows-Wheeler Transform. In this paper we pr...

A Compression-Boosting Transform for Two-Dimensional Data
We introduce a novel invertible transform for two-dimensional data which has the objective of reordering the matrix so it will improve its (lossless) compression at later stages. T...
