/** @brief Performs the per-element division of the first Fourier spectrum by the second Fourier spectrum.
*
* The function cv::divSpectrums performs the per-element division of the first array by the second array.
* The arrays are CCS-packed or complex matrices that are results of a real or complex Fourier transform.
*
* @param a first input array.
* @param b second input array of the same size and type as src1 .
* @param c output array of the same size and type as src1 .
* @param flags operation flags; currently, the only supported flag is cv::DFT_ROWS, which indicates that
* each row of src1 and src2 is an independent 1D Fourier spectrum. If you do not want to use this flag, then simply add a `0` as value.
* @param conjB optional flag that conjugates the second input array before the multiplication (true)
* or not (false).
