norm1 function

double norm1(
  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

double norm1(
  InputArray src1,
  InputArray src2, {
  int normType = NORM_L2,
  InputArray? mask,
}) {
  return cvRunArena<double>((arena) {
    final p = arena<ffi.Double>();
    mask ??= Mat.empty();
    cvRun(() => cffi.NormWithMats(src1.ref, src2.ref, normType, mask!.ref, p));
    return p.value;
  });
}
