The present disclosure relates to methods and devices for fingerprint recognition. In an aspect, a method of a fingerprint sensing system of extracting at least one fingerprint descriptor from an image captured by a fingerprint sensor for enrolment in the fingerprint sensing system is provided. The method comprises capturing images of a finger contacting the fingerprint sensor, detecting at least one fingerprint feature in each captured image, extracting fingerprint data from an area surrounding a location of the detected feature in each captured image, and extracting a fingerprint descriptor by performing a transform of the fingerprint data extracted from the area surrounding the location of the detected feature in each captured image, wherein a size of the area is selected such that the area comprises sufficient information to allow a duplicated descriptor to be discarded for the captured images.

Single-feature fingerprint recognition

3D modeling of an object using textural features. Disclosed is a method and a system for 3D modeling of a 3D object adapted to be inserted in or worn by a patient. The 3D modeling applies information of one or more features from an acquired 2D digital representation including textural data of the location where the 3D object is adapted to be arranged.

The present invention generally relates to a method for analyzing biometric measurements of a user, and specifically to determination of an alignment level between features of different biometric measurements acquired using a biometric sensor. The invention also relates to a corresponding fingerprint sensing system and to a computer program product.
