Abstract

A method for processing a test image showing a test fingerprint, the method including the following computer-implemented steps: estimating a first test inter-ridge distance relating to the test fingerprint, the first test inter-ridge distance being a distance in pixels; obtaining a reference inter-ridge distance relating to a reference fingerprint shown in a reference image, the reference inter-ridge distance being a distance in pixels; resizing the test image into a resized test image such that the first test inter-ridge distance in pixels corresponds to the reference inter-ridge distance in pixels; and commanding a comparison between the resized test image and the reference image, so as to verify whether the test fingerprint and the reference fingerprint match.
