with getOptimalDFTSize.
The function performs the following equations:
- First it applies a Hanning window (see <https://en.wikipedia.org/wiki/Hann_function>) to each
image to remove possible edge effects. This window is cached until the array size changes to speed
up processing time.
- First it applies a Hanning window to each image to remove possible edge effects, if it's provided
by user. See @ref createHanningWindow and <https://en.wikipedia.org/wiki/Hann_function>. This window may
be cached until the array size changes to speed up processing time.
- Next it computes the forward DFTs of each source array:
\f[\mathbf{G}_a = \mathcal{F}\{src_1\}, \; \mathbf{G}_b = \mathcal{F}\{src_2\}\f]
where \f$\mathcal{F}\f$ is the forward DFT.
