Abstract
A method of recognizing fingerprints, an apparatus and a terminal device are provided. The method of recognizing fingerprints includes following operations. A fingerprint image is acquired and the fingerprint image matches with pre-stored fingerprint templates. The fingerprint image is divided into a plurality of pixel regions if the fingerprint image matches with the at least one of pre-stored fingerprint templates. A number of the pixel regions having white points is computed to determine whether the fingerprint image is successfully recognized. The method of recognizing fingerprints determines whether the fingerprint image is a false fingerprint to improve fingerprint recognition accuracy. Therefore, the fingerprint recognition of the present disclosure satisfies usage convenience and provides fingerprint password security for users.
