A fractal analysis toolbox for signal and image processing

fraclab-2.1

FracLab is a general purpose signal and image processing toolbox based on fractal and multifractal methods.

FracLab can be approached from two different perspectives:

  • Fractal analysis : A large number of procedures allow to compute various fractal quantities associated with 1D or 2D signals, such as dimensions, Holder exponents or multifractal spectra.
  • Signal processing : Alternatively, one can use FracLab directly to perform many basic tasks in signal processing, including estimation, detection, denoising, modelling, segmentation,classification, and synthesis.

Note that FracLab is not intended to process "fractal" signals (whatever meaning is given to this word), but rather to apply fractal tools to the study of irregular but otherwise arbitrary signals.

A graphical interface makes FracLab easy to use and intuitive. In addition, various wavelet-related tools are available in FracLab.

System

FracLab is a free software developed in the Regularity team at Inria Saclay/Ecole Centrale de Paris.

It mainly consists of routines developed in Matlab version 7.7 (R2008a) and some routines developed in C-code. It runs under Windows, Mac OSX and Linux environments.

Since Fraclab 2.02 it exists a stand alone version that it runs under Windows, Mac OSX and Linux environments.
