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.
