1. 1. Detecting Images Outside Training Distribution for Fingerprint Spoof Detection

   University essay from Lunds universitet/Matematik LTH

   Author : Daniel Holmkvist; [2023]
   Keywords : Machine learning; Out-of-Distribution; Deep Neural Network; spoof detection; Neural Network; Mathematics and Statistics;

   Abstract : Artificial neural networks are known to run into issues when given samples that deviate from the training distribution, where the network may confidently provide an incorrect answer. Out-of-distribution detection methods aims to provide a solution to this issue, by detecting data that deviates from the distribution used to train the model. READ MORE

3. 2. Biometrics - Evaluation of Current Situation

   University essay from Informationskodning

   Author : Salman Zahidi; [2011]
   Keywords : Biometrics Evaluation Information Security;

   Abstract : Information security has always been a topic of concern in the world as an emphasis on new techniques to secure the identity of a legitimate user is regarded as top priority. To counter such an issue, we have a traditional way of authentication factors “what you have” and “what you know” in the form of smart cards or passwords respectively. READ MORE

4. 3. Extraction and Application of Secondary Crease Information in Fingerprint Recognition Systems

   University essay from Institutionen för teknik och naturvetenskap

   Author : Pontus Hymér; [2005]
   Keywords : Datorteknik; biometrics; fingerprint analysis; feature extraction; secondary creases; template aging; Gabor filter; pattern recognition; Hough transform; vector clustering; Datorteknik;

   Abstract : This thesis states that cracks and scars, referred to as Secondary Creases, in fingerprint images can be used as means for aiding and complementing fingerprint recognition, especially in cases where there is not enough clear data to use traditional methods such as minutiae based or correlation techniques. A Gabor filter bank is used to extract areas with linear patterns, where after the Hough Transform is used to identify secondary creases in a r, theta space. READ MORE

5. 4. Minutiae Extraction from Fingerprint with Neural Network and Minutiae based Fingerprint Verification

   University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

   Author : Josef Ström Bartunek; [2004]
   Keywords : Biometrics; Fingerprints; Neural Networks; Binarization; Skeletonization; Point Pattern Matching;

   Abstract : Human fingerprints are rich in details called minutiae, which can be used as identification marks for fingerprint verification. The goal of this thesis is to develop a complete system for fingerprint verification through extracting and matching minutiae. READ MORE
