public class SoComplexCenteredFFTProcessing
extends SoImageVizEngine

SoComplexCenteredFFTProcessing engine SoComplexCenteredFFTProcessing computes the centered fast Fourier transform.

For an introduction, see:

• section Frequency
• Introduction for FFT

The SoComplexCenteredFFTProcessing transformation is used to visualize the modulus of the FFT centered in the middle of image rather than in the upper left corner. The image is centered by a translation in circular mode by a vector equal to half the diagonal of the image. In the figure below, to visualize the image, it is divided in four equal quadrants.
