dftAsync function

Future<Mat> dftAsync(
  1. InputArray src, {
  2. int flags = 0,
  3. 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, {
  int flags = 0,
  int nonzeroRows = 0,
}) async =>
    cvRunAsync((callback) => cffi.core_DFT_Async(src.ref, flags, nonzeroRows, callback), matCompleter);
