1. 6. Fingerprint Segmentation

   University essay from Datateknik

   Author : Diala Jomaa; [2009]
   Keywords : Biometric system; fingerprint Recognition System; Otsu; Split and Merge; Histogram Equalization; mean; variance and coherence;

   Abstract : In this thesis, a new algorithm has been proposed to segment the foreground of the fingerprint from the image under consideration. The algorithm uses three features, mean, variance and coherence. Based on these features, a rule system is built to help the algorithm to efficiently segment the image. READ MORE

3. 7. Examination of Various Approaches to Possibly Improve the Existing Algorithms Applied in Fingerprint Recognition Systems

   University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

   Author : Gorka Treceño Fontecha; Beatriz Mora Barbero.; [2007]
   Keywords : Fingerprint Recognition;

   Abstract : In human fingerprints there are plenty of small details which are the discontinuities in the ridges, denoted minutiae. Minutiae-based matching is a wellknown method applied in fingerprint recognition. Minutiae defines a representative feature vector of a fingerprint. READ MORE

4. 8. 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. 9. Biometric methods and mobile access control

   University essay from Blekinge Tekniska Högskola/Avdelningen för programvarusystem

   Author : Linda Fransson; Therese Jeansson; [2004]
   Keywords : Biometrics; iris scan; iris; speaker verification; voice; fingerprint recognition; fingerprint; mobile phone; access control;

   Abstract : Our purpose with this thesis was to find biometric methods that can be used in access control of mobile access. The access control has two parts. Firstly, to validate the identity of the caller and, secondly, to ensure the validated user is not changed during the session that follows. READ MORE

6. 10. 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
