knnMatchAsync method

Future<VecVecDMatch> knnMatchAsync(
  1. Mat query,
  2. Mat train,
  3. int k
)

KnnMatch Finds the k best matches for each descriptor from a query set.

Implementation

Future<VecVecDMatch> knnMatchAsync(Mat query, Mat train, int k) async {
  final ret = calloc<cvg.VecVecDMatch>();
  return cvRunAsync0(
    (callback) => cfeatures2d.cv_FlannBasedMatcher_knnMatch(ref, query.ref, train.ref, k, ret, callback),
    (c) {
      return c.complete(VecVecDMatch.fromPointer(ret));
    },
  );
}
