    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : BJÖRN HEGSTAM; [2013]
    Keywords : ;

    Abstract : OptoNova is a world leading producer of inspection systems for quality control of surfaces and edges at high rates. They develop their own sensor systems and software and have taken an interest in investigating the possibility of using methods from machine learning to make better use of the available sensor data.

  3. 7. A Hardware Architecture for Scale-space Extrema Detection

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

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

    Abstract : 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. READ MORE

  4. 8. Three dimensional object recognition for robot conveyor picking

    University essay from Institutionen för systemteknik

    Author : Gustav Wikander; [2009]
    Keywords : object recognition; laser triangulation; occlusion; edge; scale-space; rotation; tilt; robot;

    Abstract : Shape-based matching (SBM) is a method for matching objects in greyscale images. It extracts edges from search images and matches them to a model using a similarity measure. In this thesis we extend SBM to find the tilt and height position of the object in addition to the z-plane rotation and x-y-position. READ MORE

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

    University essay from Institutionen för teknik och naturvetenskap

    Author : Karl Larsson; [2004]
    Keywords : 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;

    Abstract : 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. READ MORE
