A Modified Burrows-Wheeler Transform Compression Algorithm Based On Least Frequently Used Replacement
Yaqiong Liu · Microcomputer applications · 2008
Burrows-Wheeler Transform Algorithm is a widely noticed lossless compression algorithm based on block sorting.It consists sof Burrows-Wheeler Transform,Move To Front Transform and Entropy Coder.We discussed its performance and then proposed a modified MTFs algorithm based on LFU buffer replacement.The experiment results show that it yields a better compression ratio than previous one.
