  1. 1. Image processing on optimal volume sampling lattices Thinking outside the box

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Elisabeth Schold Linnér; Uppsala universitet.; Uppsala universitet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BCC; FCC; aliasing; distance transform; segmentation; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : This thesis summarizes a series of studies of how image quality is affected by the choice of sampling pattern in 3D. Our comparison includes the Cartesian cubic (CC) lattice, the body-centered cubic (BCC) lattice, and the face-centered cubic (FCC) lattice. LÄS MER

  3. 2. Methods for 2D and 3D Quantitative Microscopy of Biological Samples

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Amin Allalou; Uppsala universitet.; Uppsala universitet.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Image analysis; cytmetry; model organism; zebrafish; screening; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : New microscopy techniques are continuously developed, resulting in more rapid acquisition of large amounts of data. Manual analysis of such data is extremely time-consuming and many features are difficult to quantify without the aid of a computer. LÄS MER

  4. 3. Automated Tissue Image Analysis Using Pattern Recognition

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Jimmy Azar; Uppsala universitet.; Uppsala universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tissue image analysis; pattern recognition; digital histopathology; immunohistochemistry; paired antibodies; histological stain evaluation; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Automated tissue image analysis aims to develop algorithms for a variety of histological applications. This has important implications in the diagnostic grading of cancer such as in breast and prostate tissue, as well as in the quantification of prognostic and predictive biomarkers that may help assess the risk of recurrence and the responsiveness of tumors to endocrine therapy.

  5. 4. Computerized Cell and Tissue Analysis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Azadeh Fakhrzadeh; Uppsala universitet.; Uppsala universitet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Image processing; Cell; Tissue; Segmentation; Classification; Histology; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : The latest advances in digital cameras combined with powerful computer software enable us to store high-quality microscopy images of specimen. Studying hundreds of images manually is very time consuming and has the problem of human subjectivity and inconsistency. LÄS MER

  7. 5. 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
