normAsync function

Future<double> normAsync(
  1. InputArray src1, {
  2. int normType = NORM_L2,
  3. InputArray? mask,
})

Norm calculates the absolute norm of an array.

Implementation

Future<double> normAsync(InputArray src1, {int normType = NORM_L2, InputArray? mask}) async {
  mask ??= Mat.empty();
  final p = calloc<ffi.Double>();
  return cvRunAsync0((callback) => ccore.cv_norm(src1.ref, normType, mask!.ref, p, callback), (c) {
    final rval = p.value;
    calloc.free(p);
    return c.complete(rval);
  });
}
