Abstract: A computer-implemented method for obtaining information on biometric features of a fingerprint of a user, the method comprising obtaining an image comprising an object carrying one or more biometric features of a user, the image having a size of N×M pixels, processing the image and determining information indicative at least of a presence of a biometric feature in the block and a kind of the biometric feature to obtain a result, and outputting the result identifying the information wherein the result has a form of n×m blocks of identical size and the result associates information indicative at least of a presence of a biometric feature and a kind of the biometric feature with each block, wherein N is an integer multiple of n and M is an integer multiple of m.

Abstract: Method for resizing an image, the method comprising the steps: obtaining an image of a user comprising at least one biometric identifier, wherein the biometric identifier comprises a plurality of biometric characteristics; determining a first frequency of at least part of the plurality of the biometric characteristics in the image; determining a second frequency based on the first frequency and a property of the biometric identifier; resizing the image based on a ratio of the first and the second frequency; obtaining a resized image.
