FFST - Fast Finite Shearlet Transform

Overview

The FFST package provides a fast implementation of the Finite Shearlet Transform. Following the the path via the continuous shearlet transform, its counterpart on cones and finally its discretization on the full grid we obtain the translation invariant discrete shearlet transform. Our discrete shearlet transform can be efficiently computed by the fast Fourier transform (FFT). The discrete shearlets constitute a Parseval frame of the finite Euclidean space such that

The Matlab-Version of the toolbox is available for free download at

             http://www.mathematik.uni-kl.de/~haeuser/FFST

The zip-file contains all relevant files and folders. Simply unzip the archive and add the folder (with subfolders!) to your Matlab-path.

The folder FFST contains the main files for the both directions of the transform. The included shearlets are stored in the folder shearlets. The folder helper contains some helper functions. To create simple geometric structures some functions are provided in create. See contents.m and the comments in each file for more information.

To check if everything is installed correctly run simple_example.m for testing.
