http://www.emgu.com
Performs per-element multiplication of the two CCS-packed or complex matrices that are results of real or complex Fourier transform.

Namespace: Emgu.CV
Assembly: Emgu.CV.World (in Emgu.CV.World.dll) Version: 3.1.0.2282 (3.1.0.2282)
Syntax
public static void MulSpectrums(
	IInputArray src1,
	IInputArray src2,
	IOutputArray dst,
	MulSpectrumsType flags,
	bool conjB = false
)

Parameters

src1
Type: Emgu.CVIInputArray
The first source array
src2
Type: Emgu.CVIInputArray
The second source array
dst
Type: Emgu.CVIOutputArray
The destination array of the same type and the same size of the sources
flags
Type: Emgu.CV.CvEnumMulSpectrumsType
Operation flags; currently, the only supported flag is DFT_ROWS, which indicates that each row of src1 and src2 is an independent 1D Fourier spectrum.
conjB (Optional)
Type: SystemBoolean
Optional flag that conjugates the second input array before the multiplication (true) or not (false).
