Websites with related contents and implementations

We are aware of the following websites containing implementations and literature concerned with wedgelet approximation, or more generally, with geometric multiscale image approximation.

• The matlab toolbox BeamLab200 was developed by Donoho and his collaborators; it is available at http://www-stat.stanford.edu/beamlab/ . The toolbox contains an implementation of a wedgelet approximation algorithm. In addition to that BeamLab200 contains a host of other algorithms performing ridgelet, curvelet and beamlet transforms. Also, preprint version of related papers can be downloaded.
• The website http://www-ece.rice.edu/willett/Research/software.html contains matlab implementations of greedy, coarse-to-fine wedgelet and platelet approximation algorithms, mostly in a denoising context.
• A website containing contourlet transforms, a digital implementation of the curvelet system, can be found under http://www.ifp.uiuc.edu/minhdo/software/ .
