  1. 1. Representation Learning and Information Fusion : Applications in Biomedical Image Processing

    Författare :Elisabeth Wetzer; Nataša Sladoje; Fred Hamprecht; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Representation Learning; Texture Descriptors; Equivariant Neural Networks; Contrastive Learning; Image Classification; Image Registration; Image Retrieval; Digital Pathology; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : In recent years Machine Learning and in particular Deep Learning have excelled in object recognition and classification tasks in computer vision. As these methods extract features from the data itself by learning features that are relevant for a particular task, a key aspect of this remarkable success is the amount of data on which these methods train.

  3. 2. Three-dimensional guidance for Endovascular Aortic Repair

    Författare :Giasemi Koutouzi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anatomy deformation; CBCT; EVAR; image fusion; image guidance; image registration;

    Sammanfattning : Image fusion (IF) of preoperative computed tomography (CT) with intraoperative cone-beam CT (CBCT) is a potentially powerful tool for guidance during endovascular aortic repair (EVAR). It may improve intraoperative anatomic visualization and reduce doses of radiation and contrast medium. LÄS MER

  4. 3. 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

  5. 4. Governance of Career Guidance : an enquiry into European policy

    Författare :Anki Bengtsson; Klas Roth; Maria Olson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; governmentality; governance; career guidance; career management; Michel Foucault; entrepreneurial; policy; active citizenship; civic competence; self-management; Europe; pedagogik; Education;

    Sammanfattning : The overall aim of this thesis is to enquire into and problematize the governance of career guidance and how individuals’ career management is constructed within EU policy. The empirical material consists of European policy documents produced during 2000-2015. LÄS MER

  7. 5. Guidance and Visualization for Brain Tumor Surgery

    Författare :Filipe Miguel Maria Marreiros; Örjan Smedby; Sandro Rossitti; Karin Wårdel; Anders Ynnerman; Ole Jacob Elle; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Image guidance and visualization play an important role in modern surgery to help surgeons perform their surgical procedures. Here, the focus is on neurosurgery applications, in particular brain tumor surgery where a craniotomy (opening of the skull) is performed to access directly the brain region to be treated. LÄS MER
