curvelet transform (DCTG2) implemented in CurveLab (Curvelab 2005) and the
undecimated discrete wavelet transform from the Digital Signal Processing group
of Rice University. Note that some of the DCTG2 functions have been slightly
modified to match our dictionary data structure and to implement curvelets at the
finest scale. We strongly recommend that the user download our modified ver-
sion. Both these transforms are available in a version of MCALab named MCAL-
abWithUtilities; see the dashed rectangle in Fig. 8.16. They are in the subdirec-

The functions in the
subdirectories provide fast implicit anal-
ysis and synthesis operators for all dictionaries implemented in MCALab. It is
worth noting that except for the DCTG2 with the wrapping implementation, all
