Huffman

Algorithm::Huffman is a Perl extension that implements the Huffman algorithm. SYNOPSIS use Algorithm::Huffman; my %char_counting = map {$_ => int rand(100)} (a .. z, A .. Z); # or better the real counting for your characters # as the huffman algorithm doesnt work good with random data...

Static Huffman Coding and Decoding, and Adaptive Huffman Coding and Decoding for text compression

This file contains MATLAB functions, m-files, that do Huffman coding and arithmetic coding of integer (symbol) sequences. Complete coding may be done by calling an easy to use main program (or main function), where input argument is the sequences you want to compress and the output is the...

Library and command line program for Huffman encoding and decoding both files and chunks of memory. The encoder is a 2 pass encoder. The first pass scans the data and builds the Huffman tree. The second pass encodes the data. The decoder is one pass.

Lagarith is a lossless video codec intended for editing and archiving. Lagarith offers better compression than codecs like Huffyuv, Alparysoft, and CorePNG. There are a few lossless codecs that can compress better than Lagarith, such as MSU and FFV1; however Lagarith tends to be faster than these...
