fftw library alternative

Post by cancerberosgx »

Hello, Does any body knows of an alternative library to fftw (MIT/apache like license)? Preferable that works out of the box like a drop-in replacement ? In any case, any suggestions or idea if porting another library to replace it implies a lot of work? I will start with https://software.intel.com/en-us/mkl/features/fft which seems to be compatible with fftw . Although not opensource it allows redistribution I think... any suggestion is most welcome. thanks

It would likely be a lot of work to change the use of FFTW in ImageMagick. Sorry, I do not know any replacement library of that kind. What does OpenCV use or Skimage/Scipy?
