dctAsync function

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

DCT performs a forward or inverse discrete Cosine transform of 1D or 2D array.

Implementation

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