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

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

Implementation

Future<Mat> dctAsync(InputArray src, {int flags = 0}) async =>
    cvRunAsync((callback) => cffi.core_DCT_Async(src.ref, flags, callback), matCompleter);
