RETURN TYPEvoid

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

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.

2 available overloads

divSpectrums(a: Mat, b: Mat, c: Mat, flags: number): void;

divSpectrums(a: Mat, b: Mat, c: Mat, flags: number, conjB: boolean): void;

a

first input array.

b

second input array of the same size and type as src1 .

c

Output destination, filled by the native operation. output array of the same size and type as src1 .

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.

conjB

optional flag that conjugates the second input array before the multiplication (true) or not (false).
