Computer-implemented method for obtaining information on biometric features of a user

A computing system comprising a processor and memory, wherein the memory comprises computer-executable instructions that, when executed by the processor, cause the computing system to perform a computer-implemented 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 of the one or more biometric features in a block of a plurality of blocks of the image and a kind of the biometric feature;
• and
• outputting a result of the processing, the result identifying the information, wherein the result has a form of n×m blocks of identical size, and wherein the result associates information indicative at least of the presence of the biometric feature and the kind of the biometric feature with each block of the plurality of blocks, wherein N is a first integer multiple of n and M is a second integer multiple of m;
• wherein the presence of the biometric feature is indicated with a first binary value;
• wherein the result is used to identify a user based on the blocks and identified biometric features within the blocks;
• and
• wherein the plurality of blocks have an identical size of S×T pixels, wherein S<N and T<M, and wherein S=T=4;
• and wherein the method further comprises:
• responsive to obtaining the image and prior to processing the image, determining whether N is a third integer multiple of S and M is a fourth integer multiple of T;
• and
• responsive to determining that at least one non-integer multiple is determined, resizing the image to a size N′×M′ where N′ is a fifth integer multiple of S and M′ is a sixth integer multiple of T.
