..., Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression. The specification of the Brotli Compressed Data Format is defined in RFC 7932. Brotli is open-sourced under the MIT License. You can download and install brotli using the vcpkg dependency manager.

libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals...

This is an exercise in some advance programming topics using a text adventure as the central result. This originally began as a project to recreate an old BASIC text adventure, on the ZX Spectrum, using Z80. After developing a very simple byte code VM to handle the game interactions, I realised that there was an opportunity to use some more advance techniques, which in turn can lead to some PC based tools.

Major looseless compression algorithms library and documentation. First project: Arithmetic, Huffman, LZ77, LZ78, LZW, RLE. Second project reimplements Deflate. Documentation explains major Entropy Compression Methods.

Partial Image Encryption encrypts the huffman encoded high frequency coefficients in a jpg image file. The encryption is done in-place so the project can eventually be ported to a Windows kernel filter driver. Just encrypting the high level frequency coefficients serves to blur the image, but almost in an artistic way. The image contents are fully recognizable, but the details are pixelated or blurred. The general purpose of this program would be for securing images on the disk or in the cloud...

Static Huffman algorithm implementation using C++/Qt. Can compress files less than 50 Mb. Execute static_build.exe and try it.

THIS PROJECT HAS BEEN MOVED TO GITHUB: http://github.com/drichardson/huffman

This software zips and unzips a .txt file, using the Huffman encoding algorithm and the list and tree data structures. The result files are named zippedFile.txt and unzippedFile.txt and can be found at the same directory as the Text Zip executable file.

This project is built for learning purposes so it's implementation is kept simple and easy to read. It has two functions to either encode or decode a file with the expectation that you will modify it to suite your needs best.

ARM7 targeted MP3 player. Fixed point 16 bit. Purpose is to buid an MP3 player with the lowest possible cost. Works on mono files (going stereo shouldn't be very complicated). Doesn't use Helix. The huffman decoding uses a clustering based algorithm.

Basic Compression Library is a portable library of well known compression algorithms, such as Huffman coding, written in standard ANSI C. It is intended to serve as a set of building blocks for specialized compression algorithms.

The algorithm allows any kind of weights (costs, frequencies), including non-numerical ones. The {0, 1, ..., n-1} alphabet is used to encode message. Built tree is n-ary one.The algorithm is based on a set of template classes : Cell(SYMBOL, WEIGHT), Node(

Help implement an industrial strength Burrows-Wheeler transform compressor! Initial release covers block-sort, MTF coding, RLE coding, Huffman coding

A Huffman Coder/Compressor.

Algorithm that can generate any given series of probabilities G, using only fair coins. The algorithm creates a Huffman tree by decomposing any probability P into a sum of probabilites Q, where each Q is a power of 1/2. Than using the coins, the tra
