2. 1. Interest Curves : Concept, Evaluation, Implementation and Applications

   Author : Bo Li; Ulrik Söderström; Haibo Li; Björn Kruse; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scale-invariance; edge; corner; curve; line; matching; object detection; signalbehandling; Signal Processing;

   Abstract : Image features play important roles in a wide range of computer vision applications, such as image registration, 3D reconstruction, object detection and video understanding. These image features include edges, contours, corners, regions, lines, curves, interest points, etc. READ MORE

4. 2. Extensions and Applications of Affine Shape

   Author : Rikard Berthilsson; Matematik LTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systems engineering; Matematik; Mathematics; density of shape; maximum likelihood; matching constraint; surface; curve; handwriting; recognition; affine shape; reconstruction; computer technology; Data- och systemvetenskap;

   Abstract : A central problem in computer vision is to reconstruct the three-dimensional structure of a scene from a set of two-dimensional images. Traditionally this is done by extracting a set of characteristic points in the scene and to compute a reconstruction of these points. READ MORE

5. 3. Laser Sheet Imaging and Image Analysis for Combustion Research

   Author : Rafeef Abu-Gharbieh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear diffusion filtering; optically dense sprays; curve evolution propagation; image sequence analysis; laser induced fluorescence; geodesic paths; level sets; LIF; optical density; spray characterization; flame propagation; laser; particle image velocimetry; spectroscopy; combustion engines; spray diagnostics; Mie scattering; flame fronts; laser attenuation; tracking; combustion diagnostics; curve matching; combustion; laser sheet imaging; PIV; time resolved imaging; segmentation;

   Abstract : This Thesis presents techniques that aim at exploiting the potential of image analysis and processing in order to solve problems of data reduction, interpolation, quantification, and interpretation within the field of experimental laser imaging of combustion processes. Combustion is the most important source of energy for power generation, heating, and transportation in the world today and its strong dominance is projected to continue in the foreseeable future.

6. 4. Investigations of temporal changes in climate and the geomagnetic field via high-resolution radiocarbon dating

   Author : Anette Mellström; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; wiggle-matching; Radiocarbon dating; 14C; 2800 cal BP; climate change; solar activity; palaeomagnetism; lake sediments; varves; post-depositional remanent magnetisation; PDRM; lock-in; peat deposits; Sweden;

   Abstract : Geological archives have shown periods of abrupt climate change in the relatively stable Holocene epoch (last ca. 11 700 years). One of these periods was around 2800 cal BP. Several records, mainly from Europe, reveal a shift towards wetter, cooler and windier conditions. READ MORE

7. 5. Outcome of treatment for scoliosis. A multi-disciplinary follow-up at least 20 years after surgery or brace treatment in patients with adolescent idiopathic scoliosis with comparison to a matching control group

   Author : Aina Danielsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; scoliosis; spinal fusion; brace treatment; radiography; magnetic resonance imaging; osteoarthritis; spirometry; outcome studies; quality of life;

   Abstract : Introduction: The long term outcome of treatment for adolescent idiopathic scoliosis (AIS), with brace or surgery, has previously not been fully established.Aims: To evaluate the outcome in terms of radiological appearance, degenerative changes, pulmonary function and different aspects of health related quality of life at least twenty years after completed treatment.
