  1. 1. Manifold learning and representations for image analysis and visualization

    University dissertation from Institutionen för medicinsk teknik

    Author : Anders Brun; Hans Knutsson; Magnus Herberthson; Carl-Fredrik Westin; Reiner Lenz; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; manifold learning; image analysis; signal processing; diffusion tensor mri; MEDICINE Physiology and pharmacology Physiology Medical informatics; MEDICIN Fysiologi och farmakologi Fysiologi Medicinsk informatik;

    Abstract : We present a novel method for manifold learning, i.e. identification of the low-dimensional manifold-like structure present in a set of data points in a possibly high-dimensional space. The main idea is derived from the concept of Riemannian normal coordinates. READ MORE

  2. 2. Manifolds in Image Science and Visualization

    University dissertation from Institutionen för medicinsk teknik

    Author : Anders Brun; Hans Knutsson; Magnus Herberthson; Carl-Fredrik Westin; Roland Wilson; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; manifold learning; image analysis; signal processing; diffusion tensor mri; TECHNOLOGY Other technology Medical engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Medicinsk teknik;

    Abstract : A Riemannian manifold is a mathematical concept that generalizes curved surfaces to higher dimensions, giving a precise meaning to concepts like angle, length, area, volume and curvature. A glimpse of the consequences of a non-flat geometry is given on the sphere, where the shortest path between two points – a geodesic – is along a great circle. READ MORE

  3. 3. Learning based segmentation and generation methods for handwritten document images

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kalyan Ram Ayyalasomayajula; Anders Brun; Filip Malmberg; Nicholas Howe; [2019]

    Abstract : Computerized analysis of handwritten documents is an active research area in image analysis and computer vision. The goal is to create tools that can be available for use at university libraries and for researchers in the humanities. READ MORE

  4. 4. Interpreting the Script Image Analysis and Machine Learning for Quantitative Studies of Pre-modern Manuscripts

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Fredrik Wahlberg; Anders Brun; Lasse Mårtensson; Ewert Bengtsson; Apostolos Antonacopoulos; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; document analysis; machine learning; image analysis; digital humanities; document dating; writer identification; text recognition; Datavetenskap; Computer Science;

    Abstract : The humanities have for a long time been a collection of fields that have not gained from the advancements in computational power, as predicted by Moore´s law.  Fields like medicine, biology, physics, chemistry, geology and economics have all developed quantitative tools that take advantage of the exponential increase of processing power over time.
