A new technique called image ray transform can highlight tubular structures with a consistency preferable to face recognition technology. Our ears get bigger with age with don’t change in structural features. Ears don’t suffer from changes in facial expression — and presumably big earrings.
Neither hair or spectacles confused the image ray transform in successfully connecting an ear with its owner, with 99.6% success rate in 252 examinations. Read on at Science Daily.
