norm function

double norm(
  1. InputArray src1, {
  2. int normType = NORM_L2,
  3. InputArray? mask,
})

Norm calculates the absolute norm of an array.

Implementation

double norm(
  InputArray src1, {
  int normType = NORM_L2,
  InputArray? mask,
}) {
  mask ??= Mat.empty();
  final p = calloc<ffi.Double>();
  cvRun(() => ccore.cv_norm(src1.ref, normType, mask!.ref, p, ffi.nullptr));
  final rval = p.value;
  calloc.free(p);
  return rval;
}
