All Implemented Interfaces:

SafeDisposable
```
public class SoComplexFFTProcessing
extends SoImageVizEngine
```
SoComplexFFTProcessing engine. SoComplexFFTProcessing computes the centered fast Fourier transform.
For an introduction, see:
- section Frequency
- Introduction To FFT
The SoComplexFFTProcessing engine computes the FFT of an image. The result is two floating point images, respectively the real and imaginary parts of the transform.
Remarks
- To compute the module and phase of the FFT, use the SoCartesianToPolarProcessing2d engine.
- Be aware that images are centered in the upper left corner.
- Use the SoComplexCenteredFFTProcessing engine to visualize a centered FFT.
