  1. 1. Statistical Segmentation and Registration of Medical Ultrasound Data

    Author : Mattias Hansson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Registration; Segmentation; Feature descriptor; Statistical image and signal processing; Medical ultrasound; Variational methods; Mixture model; Bayesian; Markov Chain Monte Carlo; Similarity measur;

    Abstract : The interpretation of ultrasonic imagery is typically not straightforward and of quite subjective nature and therefore strongly dependent on the expertise of its users. Thus the development of algorithms which aid in the interpretation of ultrasonic data is a highly relevant topic. READ MORE

  2. 2. The three-dimensional normal-distributions transform : an efficient representation for registration, surface analysis, and loop detection

    Author : Martin Magnusson; Achim Lilienthal; Wolfram Burgard; Örebro universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NDT; 3D sensing; surface representation; registration; loop detection; surface analysis; mobile robotics; localisation; mapping; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Abstract : This dissertation is concerned with three-dimensional (3D) sensing and 3D scan representation. Three-dimensional records are important tools in several disciplines; such as medical imaging, archaeology, and mobile robotics. READ MORE

  3. 3. Efficient GPU-based Image Registration : for Detailed Large-Scale Whole-body Analysis

    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; Image registration; whole-body; Radiology; Radiologi;

    Abstract : Imaging has become an important aspect of medicine, enabling visualization of internals in a non-invasive manner. The rapid advancement and adoption of imaging techniques have led to a demand for tools able to take advantage of the information that is produced. READ MORE

  4. 4. Symmetry Filters Applied to Fingerprints: Representation, Feature extraction and Registration

    Author : Kenneth Nilsson; Chalmers University of Technology; []
    Keywords : symmetry filters; multiexpert; fingerprint recognition; registration; orientation radiograms; orientation field; multiscale filtering; singular points; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : A common framework for feature extraction in fingerprints is proposed by use of certain symmetries. The proposal includes representation, filters, and filtering techniques for common features including minutiae points, singular points and the ridge and valley patterns. READ MORE

  5. 5. 'This heaving ocean of tones': nineteenth-century organ registration practice at St Marien, Lübeck

    Author : Joachim Walter; Göteborgs universitet; Göteborgs universitet; Gothenburg University; Göteborgs universitet; Gothenburg University; []
    Keywords : HUMANIORA; HUMANITIES; Hermann Jimmerthal 1809–1886 ; Karl Lichtwark 1859–1931 ; Felix Mendelssohn Bartholdy 1809–1847 ; Johann Friedrich Schulze 1793–1858 ; Edmund Schulze; Friedrich Ladegast 1818–1905 ; Lübeck St. Marien; Lübeck St. Aegidien; Schwerin Dom Cathedral ; German 19th century organ registration; orchestral registration style; registration analysis; romantic organ music; organ repertoire; organ transcription; organ building;

    Abstract : The dissertation deals with German nineteenth-century registration practice with the example of St Marien, Lübeck. The time investigated covers almost one hundred years, from 1834 until 1929 and the tenures of two organists, Hermann Jimmerthal, a student of Mendelssohn, and Karl Lichtwark, a student of Jimmerthal.
