1. Set Constraints for Local Search
Sammanfattning : 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. LÄS MER
2. A Level-set Flamelet Library Model for Premixed Turbulent Combustion
Sammanfattning : 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. LÄS MER
3. Level Set Segmentation and Volume Visualization of Vascular Trees
Sammanfattning : 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. LÄS MER
4. Segmentation Methods for Medical Image Analysis : Blood vessels, multi-scale filtering and level set methods
Sammanfattning : 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. LÄS MER
5. Variational Problems and Level Set Methods in Computer Vision - Theory and Applications
Sammanfattning : 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. LÄS MER
