  1. 1. Fingerprint image enhancement and minutiae extraction algorithm

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Letian Cao; Yazhou Wang; [2017]
    Keywords : Fingerprints; Minutiae; Algorithm; Simulation; Normalization; Segmentation; Orientation; Extraction; Binarization; Thinning;

    Abstract : This work aims to study the procedures of fingerprint identification system and to present some efficient algorithms for pre-processing and minutiae extraction. Most pre-processing steps consist of normalization, segmentation and orientation estimation, and background which focus on decreasing the variance of fingerprints, separating fore and background areas and tracking the direction of ridge lines, respectively.

  3. 2. 2D SPECTRAL SUBTRACTION FOR NOISE SUPPRESSION IN FINGERPRINT IMAGES

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Sai Venkata Satya Siva Kumar Dandu; Sujit Kadimisetti; [2017]
    Keywords : Spectral Subtraction; Peak Signal to Noise Ratio PSNR ; Structural Similarity Index SSIM .;

    Abstract : Human fingerprints are rich in details called the minutiae, which can be used as identification marks for fingerprint verification. To get the details, the fingerprint capturing techniques are to be improved. Since when we the fingerprint is captured, the noise from outside adds to it. READ MORE

  4. 3. Fingerprint Matching - Hard Cases

    University essay from Lunds universitet/Matematik LTH

    Author : Alexander Karlsson; Johan Hagel; [2016]
    Keywords : Interest point; descriptor; matching; gray scale matcher; false reject rate.; Mathematics and Statistics;

    Abstract : Today fingerprint matching software is widely used in applications such as mobile phones. Software for enrollment and verification of fingerprints is usually designed to work for "good" fingerprints, meaning that the fingerprint matching algorithms use minutiae locations. READ MORE

  5. 4. The Republic of Pemberley, a Haven for Jane Austen Addicts : A Study of a Virtual Community

    University essay from Institutionen för journalistik, medier och kommunikation (JMK)

    Author : Claudia Tenenblat; [2011]
    Keywords : virtual communities; online community;

    Abstract : The Internet is revolutionizing human communication. With it, new ways of exchanging information are created, enabling intimacy even without significant physical proximity. This thesis seeks to examine one Internet community, " The Republic of Pemberley", a virtual community in English about Jane Austen’s books and life. READ MORE

  6. 5. Implementation and Evaluation of NIST Biometric Image Software for Fingerprint Recognition

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Sainath Maddala; Sreekanth Rao Tangellapally; [2010]
    Keywords : Biometric; NIST Fingerprint Verification; MEX-File; ROC graphs.;

    Abstract : Fingerprints are rich in details which are in the form of discontinuities in ridges known as minutiae and are unique for each person. The main desire of this thesis is to implement and evaluate National Institute of Science and Technology (NIST) Biometric Image Software (NBIS) for fingerprint recognition using C language MEX-files.
