Abstract
Provided are a method for fingerprint recognition, an electronic device, and a non-transitory computer-readable storage medium. The method is applicable to the electronic device. The method includes the following. An image of a user's finger placed on a fingerprint collecting region of a display screen of the electronic device is collected as an original fingerprint image. A corrected fingerprint image is obtained according to the original fingerprint image and a predetermined foreign material image, where the predetermined foreign material image is obtained when the user's finger is not placed on the fingerprint collecting region and indicative of a foreign material on the fingerprint collecting region. Determine whether a match between the corrected fingerprint image and a pre-stored fingerprint image exists by comparing the corrected fingerprint image with the pre-stored fingerprint image. The electronic device is triggered to perform a preset action in response to that the match exists.
