  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. MACHINE VISION FOR AUTOMATICVISUAL INSPECTION OF WOODENRAILWAY SLEEPERS USING UNSUPERVISED NEURAL NETWORKS

    University essay from Datateknik

  4. 8. Ground-Based Synthetic Aperture Radar Data processing for Deformation Measurement

    University essay from KTH/Geodesi och satellitpositionering

    Author : Andreas Jungner; [2009]
    Keywords : ;

    Abstract : This thesis describes a first hands-on experience working with a Ground-Based Synthetic Aperture Radar (GB-SAR) at the Institute of Geomatics in Castelldefels (Barcelona, Spain), used to exploit radar interferometry usually employed on space borne platforms. We describe the key concepts of a GB-SAR as well as the data processing procedure to obtain deformation measurements. READ MORE

  5. 9. Implementing Efficient iterative 3D Deconvolution for Microscopy

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Ahmed Shah Mehadi; [2009]
    Keywords : Iterative 3D deconvolution; Convergence rate; Boundary conditions; Point Spread function; Relaxation factor;

    Abstract : Both Gauss-Seidel Iterative 3D deconvolution and Richardson-Lucy like algorithms are used due to their stability and high quality results in high noise microscopic medical image processing. An approach to determine the difference between these two algorithms is presented in this paper. READ MORE

  6. 10. En känsla av ljud : den subtila och platsanpassade ljudinstallationen som en del av uterummet

    University essay from SLU/Landscape Architecture (until 121231)
