  1. 1. Graph-based Methods for Interactive Image Segmentation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Filip Malmberg; Uppsala universitet.; Uppsala universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Digital image analysis; Interactive image segmentation; Fuzzy image segmentation; Image foresting transform; Graph labeling; Graph cuts; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : 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. READ MORE

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

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : Peter Holdfeldt; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atherosclerotic plaque; ultrasound; classification; dynamic programming; carotid artery; image analysis; edge detection; graph cuts;

    Abstract : 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. READ MORE

  4. 4. Graph dominators in logic synthesis and verification

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : René Krenz; KTH.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; formal verification; logic synthesis; dominators; equivalence checking; decomposition; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Abstract : This work focuses on the usage of dominators in circuit graphs in order to reduce the complexity of synthesis and verification tasks. One of the contributions of this thesis is a new algorithm for computing multiple-vertex dominators in circuit graphs. READ MORE

  5. 5. Early Vision Optimization: Parametric Models, Parallelization and Curvature

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : Petter Strandmark; Lunds universitet.; Lund University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Early vision is the process occurring before any semantic interpretation of an image takes place. Motion estimation, object segmentation and detection are all parts of early vision, but recognition is not. READ MORE
