Thanks to all who replied about FFT segmentation.

A Fourier Transform in 1D is a breakdown into the waveform component
sin/cos terms. This sin/cos waves when added approximate (v. closely) the
original waveform.

How is the 2D case explained? Is the 2D transform a sum of "planar" sin/cos
"waves", or is it more of a breakdown of the horizontal groups of vertical
transforms?
