Abstract
U ovom diplomskom radu izrađen je beskontaktni sustav za prepoznavanje otisaka prstiju. Prije svega dan je pregled dosadašnjih rješenja koji se temelje na tri metode, metoda za izdvajanje detalja, dubokim učenjem te kombinacije tih dviju metoda. Zatim je opisano predloženo rješenje u ovom radu. Budući da nije pronađen odgovarajući skup podataka za učenje neuronske mreže, izrađen je vlastiti skup podataka koji je služio za treniranje i testiranje neuronske mreže. Sustav se temelji na sijamskoj... More neuronskoj mreži koja se sastoji od dvije neuronske mreže. Sijamska neuronska mreža na ulazu prima dvije RGB slike na kojima su prikazani otisci prstiju, slike se predaju neuronskoj mreži čiji su izlazi vektori značajki. Zatim se računa euklidska udaljenost između dobivenih vektora koja predstavlja mjeru sličnosti u intervalu između 0 i 1. Izlaz iz mreže će biti bliže 1 ukoliko su otisci prstiju različiti ili bliže 0 ukoliko su otisci prstiju sličniji. Istrenirani model je implementiran na NVIDIA Jetson Nano te je izrađeno fizičko okruženje s ugrađenom kamerom i LED trakom koja služi za slikanje otisaka prstiju. Izrađena sijamska neuronska mreža evaluirana je na skupu podataka za testiranje i iz rezultata testiranja je vidljivo kako ima mjesta za napredak. Less
Abstract (english)
In this master thesis, a non-contact system for recognizing fingerprints was developed. Firstly, an overview of the previous solutions based on three methods, methods for extracting details, deep learning and a combination of these two methods is given. Then the solution proposed in this paper is described. Since no suitable data set was found for learning the neural network, an own data set was created that was used for training and testing the neural network. The system is based on a... More Siamese neural network consisting of two neural networks. Siamese neural network at the input receives two RGB images on which fingerprints are displayed, the images are given to the neural network whose outputs are feature vectors. Then the Euclidean distance between the obtained vectors is calculated, which represents a measure of similarity in the interval between 0 and 1. The output from the network will be closer to 1 if the fingerprints are different or closer to 0 if the fingerprints are more similar. The trained model was implemented on NVIDIA Jetson Nano and a physical environment was created with a built-in camera and an LED strip used for fingerprint imaging. The constructed Siamese neural network was evaluated on the test data set and the test results show that there is room for improvement. Less
