AC for text compression, code is a conversion from C written by witten Neal and Cleary " AC for DATA COMPRESSION "
Data compression via Fibonacci encoding.
Shannon-Fano Data Compression.
It can compress any kind of file up to 4 GB.
(But trying to compress an already compressed file like zip, jpg etc. can produce a (slightly) larger file though. Shannon-Fano is not the best data...
Arithmetic coding and decoding for Text Compression
Static Huffman Coding and Decoding, and Adaptive Huffman Coding and Decoding for text compression
This file contains MATLAB functions, m-files, that do Huffman coding and arithmetic coding of integer (symbol) sequences. Complete coding may be done by calling an easy to use main program (or main function), where input argument is the sequences...
This is a Line Coding Technique, used for data formating. Different Formating is done with there spectral analysis.
A simple but slow way of compression using arithmetic coding.
These functions implement the 3D SPIHT algorithm, used for the compression of 3d wavelet coefficients. Such 3d wavelet coefficients are produced during the coding of video sequences.
The SPIHT method is not a simple extension of traditional methods for image compression, and represents an important advance in the field. The method deserves special attention because it provides the following:
Highest Image Quality
My functuin contains:-
1- huffman coding
2- huffman decoding
this program used for data compressin or coding
High efficient Data Compression Library for use with Delphi, C++ or VB. Support Rank, ZIP, BZIP and PPM compression algorithms. Compression ratio more than 1.5-2 times better than ZIP/RAR archiver. Compression speed up to 8 Mb/sec (on PIII-600).
EYPID - Embed Your Protein Interaction Data - Goal of the project is the adoption or definition of a logical model to describe and encode proteins interaction data into a standard XML format and the development of a web tool for easy coding the data.
It is a matlab function that codes a string of char with Arithmetic coding.
res=arithmetic_code(alphabet, distr_pr, string)
'alphabet' is a vector that contains the char used in the string 'string'; 'string' is the string to...
SMOOTHN provides a fast, unsupervised and robust discretized spline smoother for data of any dimension.
SMOOTHN(Y) automatically smoothes the uniformly-sampled array Y. Y can be any N-D noisy array (time series, images, 3D data,...).
PLS-DA for data analysis in chemistry and OMICS studies. Also included in this package are 3 variable selection methods:
1) target projection (TP)
2) competitive adaptive reweighted sampling (CARS)
Seasonal Kendall Trend Test for Data with and without Searial Dependance.
Tau-b seasonal: takes into account ties (and multiple observations, except, the data are preprocessed in a subfucntion and multiple observatiosn per a given...
A framework for data-flow based program analysis, implemented as a set of Java APIs. By using this framework, researchers and developers can easily implement analyses, test their correctness, and evaluate their performance. In addition, the...
HOW TO: Implement Key-Based Dependencies for Data Caching in ASP.NET by Using Visual C# .NET is a web based tutorial that deals with caching data technique using key based dependencies to cache data from the server. Here author discusses about...
High performance data compression and data encryption library. The archive format of this library is 100%compatible to the SQX archive format that is used in SpeedProject's latest Squeez and SpeedCommander, the compression ratios are similar to...
