Software

We are strong supporters of reproducible research, following the statement above by David L. Donoho. Thus, all MATLAB-code related to our publications as well as additional MATLAB-code for simulations will be included here as it becomes available.

If you use or mention this code in a publication, please cite www.shearlab.org as well as the following paper:

• ShearLab3D v1.1 (current version)
• ShearLab3D Manual
• 2D Experiments (denoising, inpainting, separation)
• 3D Experiments (denoising, inpainting)
• Numerical Experiments from "ShearLab 3D: Faithful Digital Shearlet Transforms Based on Compactly Supported Shearlets"
• ShearLab3D v1.01 (older version)

• Full support and unified treatment of 2D and 3D data.
• Optimized for CUDA (requires MATLAB Parallel Processing Toolbox and CUDA capable NVidia graphics card)
• Shearlets are compactly supported in the time domain.
• Examples for applications like image and video denoising, inpainting and geometric separation problems.

• pyShearLab is a Python toolbox that implements a 2D Shearlet transform based on ShearLab 3D.

• Shearlab.jl provides an implementation of ShearLab 3D in Julia. Currently only 2D transforms are available but an extension to 3D is planned for the future.

• Shearlab.jl (further information and download)
• Fwt.jl (wavelet package by the same author)

• tfShearlab provides an implementation of ShearLab 3D in tensorflow. In this case images and coefficients are considered two-dimensional tensors. This implementation is the fastest so far due to the GPU functionalities in tensorflow and is ideal to use when doing the shearlet transform in a deep learning application.

• This library can be used stand-alone or as "add-on" to ShearLab. In the latter case, extract the archive in the root directory of ShearLab. The new files have the prefix BL. See BLcontents.m and the files BL*.m in the Examples folder for details.
