norm1Async function

Future<double> norm1Async(
  1. InputArray src1,
  2. InputArray src2, {
  3. int normType = NORM_L2,
  4. InputArray? mask,
})

Norm calculates the absolute difference/relative norm of two arrays.

Implementation

Future<double> norm1Async(
  InputArray src1,
  InputArray src2, {
  int normType = NORM_L2,
  InputArray? mask,
}) async {
  final p = calloc<ffi.Double>();
  mask ??= Mat.empty();
  return cvRunAsync0(
    (callback) => ccore.cv_norm_1(src1.ref, src2.ref, normType, mask!.ref, p, callback),
    (c) {
      final rval = p.value;
      calloc.free(p);
      return c.complete(rval);
    },
  );
}
