6. Automatic Shape Modelling with Applications in Medical Imaging
Sammanfattning : This thesis consists of two parts. The first part is devoted to automatic shape analysis and the second part is devoted to decision support systems in medical imaging. Shape models are widely used in segmentation and shape analysis. The thesis begins with a review of deformable models and the preliminaries of shape modelling. LÄS MER
7. Parabolic equations with low regularity
Sammanfattning : In this work we study a variational method for treating parabolic equations that yields new results for non-linear equations with low regularity on source and boundary data. We treat mainly strongly parabolic quasilinear equations and systems in divergence form. LÄS MER
8. Inverse scattering and distribution of resonances on the real line
Sammanfattning : We study aspects of scattering theory for the Schrödinger operator on the real line. In the first part of the thesis we consider potentials supported by a half-line, and we are interested in the inverse problem of reconstruction of the potential from the knowledge of values of the reflection coefficient at equidistributed points on the positive imaginary axis.

9. Computer Vision Using Rich Features - Geometry and Systems
Sammanfattning : In this thesis a number of computer vision problems is discussed, in particular we study the problem of view synthesis. The focus is on using complex features to determine the geometry of the scene and the cameras, in contrast to traditional point-based methods. LÄS MER
10. Geometry and Critical Configurations of Multiple Views
Sammanfattning : This thesis is concerned with one of the core problems in computer vision, namely to reconstruct a real world scene from several images of it. The interplay between the geometry of the scene, the cameras and the images is analyzed. LÄS MER
