  1. 1. Chromosomal DNA Barcode Assembly Using Hierarchical Clustering Matrix Method: Including Elastic Matching

    Kandidat-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Erik Clarkson; [2020]
    Nyckelord :DNA barcoding; Physics and Astronomy;

    Sammanfattning : Obtaining DNA sequences is a time-consuming task, which typically requires one or several days for completion. One way of reducing analysis times is to be satisfied with long-range sequence patterns on the order of thousands of base pairs. DNA barcoding is a DNA-characterising technique that works according to this principle. LÄS MER

  3. 2. Application of convolutional neural networks for fingerprint recognition

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Tuong Lam; Simon Nilsson; [2018]
    Nyckelord :convolutional neural network; CNN; neural network; fingerprint; matching; siamese; inception; triplet; capsule; Mathematics and Statistics;

    Sammanfattning : Fingerprint recognition is a well-known problem in pattern recognition and widely used in contemporary authentication technology such as access devices in mobile phones. The subject of this thesis is to investigate the applicability of convolutional neural networks for fingerprint recognition. LÄS MER

  4. 3. 2D SPECTRAL SUBTRACTION FOR NOISE SUPPRESSION IN FINGERPRINT IMAGES

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

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

    Sammanfattning : 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. LÄS MER

  5. 4. Fingerprint Matching - Hard Cases

    Master-uppsats, Lunds universitet/Matematik LTH

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

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

    Sammanfattning : 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.
