dftAsync function

Future<Mat> dftAsync(
  1. InputArray src, {
  2. OutputArray? dst,
  3. int flags = 0,
  4. int nonzeroRows = 0,
})

DFT performs a forward or inverse Discrete Fourier Transform (DFT) of a 1D or 2D floating-point array.

Implementation

Future<Mat> dftAsync(InputArray src, {OutputArray? dst, int flags = 0, int nonzeroRows = 0}) async {
  dst ??= Mat.empty();
  return cvRunAsync0(
    (callback) => ccore.cv_dft(src.ref, dst!.ref, flags, nonzeroRows, callback),
    (c) {
      return c.complete(dst);
    },
  );
}
