A method of filtering fingerprint candidates, the method being carried out by an indexing module arranged to access a Convolutional Neuronal Network, CNN configured to output at least one feature of an input image. The method comprises processing an image representative of local information of a searched fingerprint, by the CNN to obtain at least one feature for the searched fingerprint; retrieving a candidate fingerprint in a database; determining whether at least one feature of the retrieved candidate fingerprint matches with the at least one feature of the searched fingerprint; if the at least one feature of the retrieved candidate fingerprint matches with the at least one feature of the searched fingerprint, passing the at least one candidate fingerprint to a matching module for further comparison between the candidate fingerprint and the searched fingerprint. Other aspects are also considered.
A method of filtering a fingerprint candidate, the method being carried out at least by an indexing module arranged to access a Convolutional Neuronal Network (CNN) that is configured to receive an image and to output at least one feature of said image, the method comprising the following steps:
