A Win32 library implementing the FFT Block Matching Algorithm can be
downloaded here:

fftbma.zip

Note that this library does not included FFTW. For the latest
version of FFTW please visit www.fftw.org.
For the FFTBMA library to work, the FFTW library needs to be compiled
into a DLL that implements real transforms. To
simplify this process, we have included a MSVC++ 6.0 project that can
be used to compile the FFTW library as required. Just extract
the following zip file into the base directory of your FFTW
distribution:

rfftwdll.zip

The above project exports only those FFTW functions required for
the FFTBMA binary distribution to work. If a general purpose
compilation of FFTW is needed, then a more complete export definition
is needed.
