    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Spectral Relaxation; Normalized Cuts; Continuous Cuts; Segmentation; Generalized Convexity; 3D-Reconstruction; Global Optimization; Multiple View Geometry; Trust Region Subproblem;

    Sammanfattning : Computer vision is today a wide research area including topics like robot vision, image analysis, pattern recognition, medical imaging and geometric reconstruction problems. Over the past decades there has been a rapid development in understanding and modeling different computer vision applications. LÄS MER

  3. 2. On the logic of pattern cutting : foundational cuts and approximations of the body

    Författare :Rickard Lindqvist; Högskolan i Borås; []
    Nyckelord :HUMANIORA; HUMANITIES; Textiles and fashion; Textiles and Fashion General ; Textil och mode generell ;

    Sammanfattning : Fashion designers are presented with a range of different principles for pattern cutting and the interest in this area has grown rapidly over the past few years, both due to the publication of a number of works dealing with the subject in different ways and the fact that a growing number of designers emphasise cutting in their practices. Although a range of principles and concepts for pattern cutting are presented from different perspectives, the main body of these systems, traditional as well as contemporary, are predominately based on a quantified approximation of the body.

  4. 3. Dynamic Programming for Ultrasound Image Analysis of Atherosclerosis

    Författare :Peter Holdfeldt; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atherosclerotic plaque; ultrasound; classification; dynamic programming; carotid artery; image analysis; edge detection; graph cuts;

    Sammanfattning : Cardiovascular diseases, due to atherosclerosis, are among the most common causes of death in the industrialized world. Atherosclerotic plaque composition as well as arterial diameter and wall thickness can be used to predict the risk of cardiovascular disease. These risk factors can be assessed non-invasively by ultrasound. LÄS MER

  5. 4. Graph-based Methods for Interactive Image Segmentation

    Författare :Filip Malmberg; Ingela Nyström; Ewert Bengtsson; Jayaram K. Udupa; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Digital image analysis; Interactive image segmentation; Fuzzy image segmentation; Image foresting transform; Graph labeling; Graph cuts; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : The subject of digital image analysis deals with extracting relevant information from image data, stored in digital form in a computer. A fundamental problem in image analysis is image segmentation, i.e., the identification and separation of relevant objects and structures in an image. LÄS MER

  7. 5. Investigating Dwellings' Response to Heating Power Cuts : Simulations and Field Tests

    Författare :Victor Fransson; Avdelningen för Installations- och klimatiseringslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Reducing energy use, increasing the use of renewable energy sources, and adapting to stricter building regulations and certification systems – these are all examples of the challenges facing the building industry and society. Looking at the energy supply at a larger scale than a single building, like a neighborhood or a city, the stack effect of peak power demands can cause problems on the production side, either economical or concerning the environment and greenhouse gases when fossil fuel is used to cover these peaks.
