  1. 1. Group-Theoretical Structure in Multispectral Color and Image Databases

    Författare :Thanh Hai Bui; Reiner Lenz; Björn Kruse; Jinhui Chao; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; group theory; PCA Principal Component Analysis ; CBIR; Content-based Image Retrieval ; filter; color; image; multispectral; database; Signal processing; Signalbehandling;

    Sammanfattning : Many applications lead to signals with nonnegative function values. Understanding the structure of the spaces of nonnegative signals is therefore of interest in many different areas. Hence, constructing effective representation spaces with suitable metrics and natural transformations is an important research topic. LÄS MER

  3. 2. Digital Image Analysis of Cells : Applications in 2D, 3D and Time

    Författare :Amalka Pinidiyaarachchi; Carolina Wählby; Ewert Bengtsson; Arvid Lundervold; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Digital image analysis; microscopy; fluorescent staining; watershed segmentation; sub-cellular localization; point-like signals; wavelets; cell confluence; cytology; color spaces.; Image analysis; Bildanalys;

    Sammanfattning : Light microscopes are essential research tools in biology and medicine. Cell and tissue staining methods have improved immensely over the years and microscopes are now equipped with digital image acquisition capabilities. The image data produced require development of specialized analysis methods. LÄS MER

  4. 3. Non-Euclidean structures in PCA-based descriptions of multispectral databases

    Författare :Hai Thanh Bui; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Traditional color science is based on human color vision. For many applications (for example remote sensing, medical imaging, industrial inspection) where spectral properties of the radiation are of interest, human color vision based systems are too restrictive. Therefore multispectral approaches are becoming more and more popular. LÄS MER

  5. 4. from [al'manja] with love : Trans_ feministische Positionierungen zu Rassismus und Migratismus

    Författare :Alyosxa Tudor; Nina Lykke; Michelle Wright; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Racism; migratlsm; nationalism; diaspora; trans politlcs; transgender; transnational feminism; postcolonlal studies; decolonial studies; crltical migration studies; migration; Europe Germany; transnationalism; Rasism; migratism; nationalism; diaspora; transpolittska; transgender; transnationell feminism; postcolonial studies; decolonial studies; kritiska migrationsstudier; migration; Europa; Tyskland; transnationalism;

    Sammanfattning : from [al'manja} with love revisits Critical Migration Studies with the insights of postcolonial and decolonial approaches and carves out a perspectlve on power relations that brlngs together transnational feminism and 'trans(gender) polltics'.I dlscuss what racism and migratlsm mean in a German and European context, and work out how they shape hegemonlc understandings of 'Germany' and 'Europe'.

  7. 5. Tackling the Uncertainties of Event Generators

    Författare :Leif Gellersen; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QCD; Phenomenology; Parton Showers; Matrix Element Merging; Tuning;

    Sammanfattning : This thesis is composed of four papers, which concern Monte Carlo event generators for high energy particle physics. Precise predictions of the outcome of particle collisions are important for the exploration of the Standard Model of particle physics at collider experiments like the LHC at CERN. LÄS MER
