Documentation

Applied on a scalar image, computes the direct Discrete Fourrier Transform (DFT) and return a 2 components vectorial image whose first component is real coefficients and second components is imaginary coefficients of DFT. Applied on a 2 components vectorial image, this function computes the inverse DFT and returns a scalar coefficient assuming that the result is real.

Throws:

InvalidSize in DFT-1, image size is not a power of 2

Parameters:

twoD - 2D (slice by slice) DFT computation if true, 3D DFT otherwise
