1. 1. 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. 2. 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

4. 3. 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

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. 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
