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.

JDIFF is a program that outputs the differences between two binary files, either in binary format or in human readable format (detailed or summarized) and then allows to reconstruct the second file from the first one and the diff-file.

Slim is a data compression system for scientific data sets, a binary and a library with C linkage. Slim works with integer data from one or more channels in a file, which it can compress more effectively and more rapidly than general tools like gzip.

BNS - Burris Numerical System was written to store the last digit of a number in 3 dimensional space but store the rest of the number mathematically in the 4th dimension of space. The result is that no matter how long the number is you can write it down on a piece of paper and put it in your pocket. The software can be used to retrieve the number. This can be used to save computer files. The only limit with BNS is how much time the user has. The software nor the numerical system has no...

SEG-Y files need special compression because they don't compress well using gzip and the like. The code is cross-platform C++ using nothing else than standard system libraries. This is a spin-off from the OpendTect project (http://opendtect.org).

PyramidWorkshop is an image-compression System based upon the scientific work of John Robinson (inventor of BTPC) about image-compression with adaptive linear predictors and is in average more efficient than PNG/JPEG2000.

StormRT is a real-time multi-resolution analysis and compression package for data compression and temporal feature detection over multiple timescales.

PileWorks provides the organizational structure for coordinating several different projects which approach some aspect of Pile Technology. PileWorks defines a set of interfaces and implements some basic infrastructure for Pile engines and agents.

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(

Numerically estimate an efficiency of code construction algorithms. Randomly generate n binary words of length m with minimum Hamming distance d and create a prefix code (= retrieval tree) from them. Based on PhD work.

quaneko is a tool that allows you to quickly search for keywords in files on the harddisk. It creates indexes over all files in given directories. A typical search query takes only seconds. Support for various file formats can be easily configured.

A signal-based file translator and manipulator, designed for supporting any data file format used to store signal data, built to translate to and from MiniMitter's VitalView, Actimetrics' ClockLab, Flaga's Embla Somnologica and Udicus' own UDCS format.
