Data compression projects and source code

Huffmancompressioncode in java

The following java project contains the java source code and java examples used for huffman_compression_code. The Huffman Compression Algorithm is essentially one that compresses any string entered by the user. This makes it easier to transfer data and much more convinent because it can be reassembled on the receiving end.

Gzipper in java

The following java project contains the java source code and java examples used for gzipper. GZipper is a zipping/unzipping program written in java.it works on jdk1.3 and above.It can be used for zipping only one file at a time now.The gzip format can be read using many popular zipping programs like winrar etc.

Eve - file compression utility in java

The following java project contains the java source code and java examples used for eve - file compression utility. Eve,is a File Compression Utility. (Swing Interface) Eve, currently supports 7 Compression Algorithms. Huffman, Shannon-Fano, GZip, LZW, RLE, Fixed Length Encoding (Cosmo), Junkcode Binary Compression (JBC) Includes FileBitIO Package that allows you to read/write from Files bitwise...

Rapid lossless data compression of numerical or string variables in matlab

The following Matlab project contains the source code and Matlab examples used for rapid lossless data compression of numerical or string variables. Using the public domain ZLIB Deflator algorithm, these two functions (DZIP and DUNZIP) losslessly compress or decompress MATLAB variables of most data types so that they occupy less space.

Huffman Coding Matlab Code

Huffman code is an optimal prefix code found using the algorithm developed by David A. Huffman while he was a Ph.D. student at MIT, and published in the 1952 paper "A Method for the Construction of Minimum-Redundancy Codes". The process of finding and/or using such a code is called Huffman coding and is a common technique in entropy encoding, including in lossless data compression. The algorithm's output can be viewed as a variable-length code table for encoding a source symbol (such as a character in a file).
