  1. 1. Image Filtering Methods for Biomedical Applications

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :M. Khalid Khan Niazi; Uppsala universitet.; Uppsala universitet.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital image analysis; Image filtering; Intensity inhomogeneity correction; Empirical mode decomposition; Particle Swarm optimization; Image registration; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Filtering is a key step in digital image processing and analysis. It is mainly used for amplification or attenuation of some frequencies depending on the nature of the application. Filtering can either be performed in the spatial domain or in a transformed domain. LÄS MER

  2. 2. Automatic Virus Identification using TEM Image Segmentation and Texture Analysis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Gustaf Kylberg; Uppsala universitet.; Uppsala universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image analysis; image processing; virus identification; transmission electron microscopy; texture analysis; texture descriptors; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Viruses and their morphology have been detected and studied with electron microscopy (EM) since the end of the 1930s. The technique has been vital for the discovery of new viruses and in establishing the virus taxonomy. Today, electron microscopy is an important technique in clinical diagnostics. LÄS MER

  3. 3. Image Analysis in Support of Computer-Assisted Cervical Cancer Screening

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Patrik Malm; Uppsala universitet.; Uppsala universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Image analysis; cervical cancer; pap-smear; synthetic images; screening; image processing; cytometry; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Cervical cancer is a disease that annually claims the lives of over a quarter of a million women. A substantial number of these deaths could be prevented if population wide cancer screening, based on the Papanicolaou test, were globally available. The Papanicolaou test involves a visual review of cellular material obtained from the uterine cervix. LÄS MER

  4. 4. Spectral Image Processing with Applications in Biotechnology and Pathology

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Milan Gavrilovic; Uppsala universitet.; Uppsala universitet.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; color theory; light microscopy; spectral imaging; image analysis; digital image processing; mathematical modeling; estimation; noise models; spectral decomposition; color decomposition; colocalization; cross-talk; autofluorescence; tissue separation; prostate cancer; biomedical applications; molecular biotechnology; histopathology; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Color theory was first formalized in the seventeenth century by Isaac Newton just a couple of decades after the first microscope was built. But it was not until the twentieth century that technological advances led to the integration of color theory, optical spectroscopy and light microscopy through spectral image processing. LÄS MER

  5. 5. Becoming Image Perspectives on Digital Culture, Fashion and Technofeminism

    Detta är en avhandling från Stockholm : Fashion Studies, Stockholm University

    Författare :Lisa Ehlin; Stockholms universitet.; [2015]
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Technology; Selfie; Embodiment; Tumblr; Memory; Instagram; Posthumanism; modevetenskap; Fashion Studies;

    Sammanfattning : Departing from a technofeminist perspective, Becoming Image, places the digital image in a broader context of modern and postmodern technological discourses and fashion. In four articles, the compilation dissertation expands a contemporary and imagistic tech discourse by questioning the ideology of ”masculinity”―specifically the idea of it as a historically male domain.
