CD image processing suite with optimized lossless encoders in C#

CharLS, a C++ JPEG-LS library implementation

A lossless compression algorithm implemented in Rust, inspired by Huffman coding

This project is a team assignment for the "Multimedia Systems" course, offered in the 6th semester of the 2023 academic year at the University of Piraeus, Department of Informatics.

In this code we implement the IEEE 1857.2 lossless audio coding extension using 3 different source coding techniques : 1) Arithmetic Coding (benchmark)

A small web app for lossless compression for text files

An implementation of a Huffman Encoding algorithm that generates a Huffman table for a given text file

This repository contains a C implementation of the Huffman coding algorithm, which is an efficient method for lossless data compression. The code constructs a Huffman tree based on the frequency of characters in a given message and generates a unique binary code for each character, minimizing the overall space required to store the message.

huff.py is a compression tool, used compress/decompress files.

A flexible Python tool for compressing data files with gzip, perfect for efficiently storing or transmitting large amounts of data without compromising quality.

Lepton is a tool and file format for losslessly compressing JPEGs by an average of 22%.
