  1. 1. Image Filtering Methods for Biomedical Applications

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :M. Khalid Khan Niazi; Ewert Bengtsson; Ingela Nyström; Lucas J. van Vliet; [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; Ida-Maria Sintorn; Gunilla Borgefors; Walter Kropatsch; [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. Spectral Image Processing with Applications in Biotechnology and Pathology

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Milan Gavrilovic; Carolina Wählby; Ewert Bengtsson; Ingrid Carlbom; Robert Murphy; [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

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

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

    Författare :Lisa Ehlin; Louise Wallenberg; Nina Lager Vestberg; [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.

  5. 5. Biological Inspired Deformable Image Sensor

    Detta är en avhandling från Karlskrona : Blekinge Tekniska Högskola

    Författare :Wei Wen; Khatibi Siamak; Coleman Sonya; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image sensor; pixel form; sub-arrangements; fill factor; square image; hexagonal image; deformable sensor; quality assessment.;

    Sammanfattning : Nowadays, cameras are everywhere thanks to the tremendous progress on sensor technology. However, their performance is far away from what we experience by our eyes. LÄS MER
