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 =>
    cvRunAsync(
      (callback) => mask == null
          ? cffi.core_Norm_Async(src1.ref, normType, callback)
          : cffi.core_Norm_Mask_Async(src1.ref, normType, mask.ref, callback),
      doubleCompleter,
    );
