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

Benchmark Test
