  2. 1. Set Constraints for Local Search

    Author : Magnus Ågren; Pierre Flener; Justin Pearson; Gilles Pesant; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; combinatorial problems; constraint-based local search; constraint-directed search; constraint programming; incremental algorithms; monadic existential second-order logic; neighbourhoods; penalty; set variables; set constraints; variable conflicts; Computer science; Datavetenskap; Datavetenskap; Computer Science;

    Abstract : Combinatorial problems are ubiquitous in our society and solving such problems efficiently is often crucial. One technique for solving combinatorial problems is constraint-based local search. Its compositional nature together with its efficiency on large problem instances have made this technique particularly attractive. READ MORE

  4. 2. A Level-set Flamelet Library Model for Premixed Turbulent Combustion

    Author : Per Nilsson; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; applied thermodynamics; Thermal engineering; Distance-function; Level-set; Flamelet Library; Flamelet; Turbulence; Premixed; Combustion; termodynamik; Gases; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma; Motors and propulsion systems; Motorer; framdrivningssystem;

    Abstract : The modelling of premixed turbulent combustion has been studied. Premixed turbulent combustion occurs in a range of applications, such as gas turbines and spark-ignition engines. READ MORE

  5. 3. Level Set Segmentation and Volume Visualization of Vascular Trees

    Author : Gunnar Läthén; Reiner Lenz; Magnus Borga; Lasse Riis Østergaard; Linköpings universitet; []
    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

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

    Author : Gunnar Läthén; Reiner Lenz; Niels Christian Overgaard; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Image segmentation; Medical image analysis; Level set method; Quadrature filter; Multi-scale; Image analysis; 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.

  7. 5. Variational Problems and Level Set Methods in Computer Vision - Theory and Applications

    Author : Jan Erik Solem; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; level set methods; computer vision; variational problems; Matematik;

    Abstract : Current state of the art suggests the use of variational formulations for solving a variety of computer vision problems. This thesis deals with such variational problems which often include the optimization of curves and surfaces. READ MORE
