The CurveletUtils package contains Matlab functions and a Matlab GUI implementing the algorithms described in the paper:
T. Gebäck, P. Koumoutsakos, Edge detection in microscopy images using curvelets, Structural Biology, 2008
In addition, a set of functions is included for working and displaying curvelet transform, including a GUI for easy thresholding and reconstruction of images.
The CurveletUtils package can be downloaded here: curveletutils.zip
The file README.txt included in the package provides installation instructions and a manual for the GUIs.
The CurveLab software has to be downloaded separately from www.curvelet.org
