  1. @override
double compare(
  1. InputArray hashOne,
  2. InputArray hashTwo
)
override

Compare compares the hash value between a and b using BlockMeanHash.

Implementation

@override
double compare(InputArray hashOne, InputArray hashTwo) {
  final p = calloc<ffi.Double>();
  cvRun(() => ccontrib.cv_img_hash_BlockMeanHash_compare(ref, hashOne.ref, hashTwo.ref, p, ffi.nullptr));
  final rval = p.value;
  calloc.free(p);
  return rval;
}
