SoComplexFFTInverseProcessing engine. The SoComplexFFTInverseProcessing engine computes the fast of Fourier inverse transform.
For an introduction, see:
- section Frequency
- Introduction for FFT
The SoComplexFFTInverseProcessing engine computes the inverse FFT of an image. The result is two floating point images, respectively the real and imaginary parts of the complex inverse Fourier Transform.
Remarks
- A classical operation is to first filter the spectrum of an image (especially to suppress high frequencies usually associated with noise), and then reconstruct the input image using SoComplexFFTInverseProcessing with the filtered spectrum and unchanged phase as input images.
- Be aware that images are centered in the upper left corner. Use the SoComplexCenteredFFTInverseProcessing engine to visualize a centered image.
- The imaginary output image of SoComplexFFTInverseProcessing is null.
