Implementation
Future<(Scalar mean, Scalar stddev)> meanStdDevAsync(InputArray src, {InputArray? mask}) async => cvRunAsync2(
(callback) => mask == null
? ccore.core_MeanStdDev_Async(src.ref, callback)
: ccore.core_MeanStdDevWithMask_Async(src.ref, mask.ref, callback),
(c, p, p1) =>
c.complete((Scalar.fromPointer(p.cast<ccore.Scalar>()), Scalar.fromPointer(p1.cast<ccore.Scalar>()))),
);
