      Description

      Try out DFT space operations to understand:

      • How to properly do convolution in DFT space in image and PSF kernel relation
      • Padding, borders, translation of originals
      • Numeric optimization of DFT, IDFT transformations by shifting significant values into the high-frequency region.
      • Demonstrate a kernel inversion (deconvolution) operation, prototype how to do this in the decorrelation afterburner
      • Ian Sullivan's hint: Check whether the above works for odd size FFT calls because odd size handling in DFT may be implementation dependent.

      Write this in a jupyter notebook.
