TL;DR

This paper introduces a size adaptive region-based Huffman compression method that divides files into variable length regions, achieving better compression ratios on certain files compared to traditional methods.

Contribution

The paper presents a novel lossless compression technique using variable length regions for improved Huffman coding efficiency.

Findings

Better compression ratios on some files

Effective region formation for Huffman coding

Comparison shows improvements over classical Huffman

Abstract

A loss-less compression technique is proposed which uses a variable length Region formation technique to divide the input file into a number of variable length regions. Huffman codes are obtained for entire file after formation of regions. Symbols of each region are compressed one by one. Comparisons are made among proposed technique, Region Based Huffman compression technique and classical Huffman technique. The proposed technique offers better compression ratio for some files than other two.
