Matlab Toolbox for Shearlets

ShearLab is a MATLAB library developed for processing two- and three dimensional data with a certain class of basis functions named shearlets. Such shearlet systems are particularly well adapted to represent anisotropic features (such as curves) that are often crucial in multidimensional data. The resulting representation has proven well-suited for image processing tasks such as inpainting, denoising or image separation. On this website we provide the full MATLAB code, a framework for numerical tests as well as general information on shearlets.

The ShearLab 3D Toolbox (Ver. 1.0) and older versions of ShearLab can be downloaded from Further, you can find ShearLab3D on the webpage of the Oberwolfach References on Mathematical Software here and on swMATH here.
