Patent number: 11823487Abstract: Method for forming an enrolled fingerprint template for a user of a fingerprint touch sensor. The method comprising: during a touch event in which a finger of the user is placed on the fingerprint sensor, capturing a plurality of images of the finger and comparing two of the images to determine if there is a valid transformation. If there is no valid transformation, images are compared against image quality and coverage thresholds to determine if any of the captured images are to be used for enrollment.Type: GrantFiled: April 29, 2021Date of Patent: November 21, 2023Assignee: FINGERPRINT CARDS ANACATUM IP ABInventors: Troels Bjerre, Peter Bjørn-Jørgensen
