Detailed Description

ImageViz SoComplexCenteredFFTProcessing engine

SoComplexCenteredFFTProcessing computes the centered fast Fourier transform.

For an introduction, see:

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.
