The Problem
ITK obtains Fast Fourier Transform (FFT) functionalities from
- VXL - as software included as third party library
- FFTW - as a configuration time option
Where is the Code
ITK classes that provide FFT filters can be found in the Module:
ITK/Modules/Filtering/FFT
They include
- itkFFTShiftImageFilter.h
- itkFFTWForwardFFTImageFilter.h
- itkFFTWInverseFFTImageFilter.h
- itkForwardFFTImageFilter.h
- itkInverseFFTImageFilter.h
- itkVnlForwardFFTImageFilter.h
- itkVnlInverseFFTImageFilter.h
- vnl_fft_3d.h
VXL
The FFT software in VXL is
