  1. 1. Segmentation Methods for Medical Image Analysis Blood vessels, multi-scale filtering and level set methods

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Gunnar Läthén; Reiner Lenz; Niels Christian Overgaard; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Image segmentation; Medical image analysis; Level set method; Quadrature filter; Multi-scale; TECHNOLOGY Information technology Image analysis; TEKNIKVETENSKAP Informationsteknik Bildanalys;

    Abstract : Image segmentation is the problem of partitioning an image into meaningful parts, often consisting of an object and background. As an important part of many imaging applications, e.g. face recognition, tracking of moving cars and people etc, it is of general interest to design robust and fast segmentation algorithms.

  2. 2. Level Set Segmentation and Volume Visualization of Vascular Trees

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Gunnar Läthén; Reiner Lenz; Magnus Borga; Lasse Riis Østergaard; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; level set methods; image segmentation; edge detection; visualization; volume rendering; blood vessels; angiography; vascular trees;

    Abstract : Medical imaging is an important part of the clinical workflow. With the increasing amount and complexity of image data comes the need for automatic (or semi-automatic) analysis methods which aid the physician in the exploration of the data. READ MORE

  3. 3. Computational Techniques for Coupled Flow-Transport Problems

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Martin Kronbichler; Gunilla Kreiss; Jean-Luc Guermond; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Finite element method; saddle point systems; two-phase flow; level set method; phase field method; stabilization; contact line dynamics; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : This thesis presents numerical techniques for solving problems of incompressible flow coupled to scalar transport equations using finite element discretizations in space. The two applications considered in this thesis are multi-phase flow, modeled by level set or phase field methods, and planetary mantle convection based on the Boussinesq approximation. READ MORE

  4. 4. A generic security evaluation method for open distributed systems

    University dissertation from Institutionen för teleinformatik

    Author : Ann Frisinger; [2001]
    Keywords : information security; security evaluation; risk analysis; method; ipen distributed system; virtual system; networked education; X-ify; NED-ify;

    Abstract : Security is an important attribute of any informationsystem. Whether your business is small or large you have to beable to set the desired security levels for your system. Anon-decided or non-fulfilled security level target can easilyend up in unplanned costs. READ MORE

  5. 5. Industrial Experiences of Set-based Concurrent Engineering- Effects, results and applications

    University dissertation from Institutionen för teleinformatik

    Author : Dag Raudberget; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Design; Design process; Set-based design; Design Decisions; Lean Product Development; Set-based Concurrent Engineering; New Product Development; Development method;

    Abstract : During product development, most of the customer value, as well as the cost and the quality of a product are defined. This key role of development in industry has led to an intense search for better ways to develop products, software, services and systems. READ MORE
