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...

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.

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(

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
