An AI that can repair blurred or distorted images of fingerprintsFingerprint, impression made by the papillary ridges on the ends of the fingers and thumbs. Fingerprints afford an infallible means of personal identification, because the ridge arrangement on every finger of every human being is unique... lifted from crime scenes could make identifying people easier, but it is unclear whether such evidence would stand up in court.
Amol Joshi at West Virginia University and his colleagues trained an AI to cancel out distortions of fingerprints caused by incorrect camera focusing and other errors.
The team took a data set of 15,860 clean fingerprint images from 250 subjects and created blurred versions of them synthetically at varying levels of distortion.
