While I think it would be great for Boost.GIL users to be able to perform Fourier transforms on their images, I'm not convinced the best way to support that would be by adding our own FFT implementations to Boost.GIL. Given the amount of work (and expertise !) that goes into existing third-party FFT libraries (such as FFTW: http://fftw.org/), I think it's far more useful to make sure Boost.GIL can readily use (or be used with) such libraries.
FYI, Boost.Math already uses FFTW for Chesbyshev polynomials.
Great to see ! Debabrata, perhaps you could look into the above and see whether Boost.GIL could use a similar technique to use FFTW as a backend. Regards, Stefan -- ...ich hab' noch einen Koffer in Berlin...
