Abstract
Methods, systems, and apparatus for operations for processing fingerprint images. An example system includes obtaining an original fingerprint trace image of a fingerprint trace left by a user on a target object; inputting the original fingerprint trace image to a pre-trained fingerprint image processing model that is configured to process the original fingerprint trace image in accordance with pre-trained parameters of the pre-trained fingerprint image processing model; obtaining as output a target fingerprint trace image from the fingerprint image processing model; and using the target fingerprint trace image as a test fingerprint image for performing a test on a fingerprint recognition device, wherein a degree of matching between a fingerprint in the target fingerprint trace image and a real fingerprint that corresponds to a same finger is greater than or equal to a predetermined threshold.
