VecVecDMatch knnMatch(
  1. Mat query,
  2. Mat train,
  3. int k
)

Implementation

VecVecDMatch knnMatch(Mat query, Mat train, int k) {
  final ret = VecVecDMatch();
  cvRun(
    () => cfeatures2d.cv_FlannBasedMatcher_knnMatch(ref, query.ref, train.ref, k, ret.ptr, ffi.nullptr),
  );
  return ret;
}
