  2. 2. A Hardware Architecture for Scale-space Extrema Detection

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Hamza Ijaz; [2012]
    Nyckelord :SIFT; computer vision; scale invariance; scale-space extrema detection; FPGA; feature detection; gaussian smoothing; separable;

    Sammanfattning : Vision based object recognition and localization have been studied widely in recent years. Often the initial step in such tasks is detection of interest points from a grey-level image. LÄS MER

  3. 3. Scale-Space Methods as a Means of Fingerprint Image Enhancement

    Uppsats för yrkesexamina på grundnivå, Linköpings universitet/Institutionen för teknik och naturvetenskap

    Författare :Karl Larsson; [2004]
    Nyckelord :Datorteknik; fingerprint; template aging; correlation; image enhancement; scale-space; Gaussian scale-space; linear scale-space; nonlinear isotropic scale-space; nonlinear anisotropic scale-space; diffusion; scalar driven diffusion; scalar dependent diffusion; tensor driven diffusion; tensor dependent diffusion; Datorteknik;

    Sammanfattning : The usage of automatic fingerprint identification systems as a means of identification and/or verification have increased substantially during the last couple of years. It is well known that small deviations may occur within a fingerprint over time, a problem referred to as template ageing. LÄS MER
