  1. 1. Segmentation and Visualisation of Human Brain Structures

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Roger Hult; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; segmentation; visualisation; brain; cortex; hippocampus; autoradiography; MRI; PET; ROI; Bildanalys; TECHNOLOGY Information technology Image analysis; TEKNIKVETENSKAP Informationsteknik Bildanalys; Computerized Image Analysis; datoriserad bildanalys;

    Abstract : In this thesis the focus is mainly on the development of segmentation techniques for human brain structures and of the visualisation of such structures. The images of the brain are both anatomical images (magnet resonance imaging (MRI) and autoradigraphy) and functional images that show blood flow (functional magnetic imaging (fMRI), positron emission tomography (PET), and single photon emission tomograpy (SPECT)).

    Abstract : This thesis presents work in digital image cytometry applied to fluorescence microscope images of cultivated cells. Focus has been on the development and compilation of robust image analysis tools, enabling quantitative measurements of various properties of cells and cell structures. READ MORE

  3. 3. Atlas-Based Fusion of Medical Brain Images Methods and Applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Roger Lundqvist; Uppsala universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; Bildanalys; TECHNOLOGY Information technology Image analysis; TEKNIKVETENSKAP Informationsteknik Bildanalys; Computerized Image Analysis; datoriserad bildanalys;

    Abstract : This thesis focuses on the development of methods for fusion of information from medical brain scans. The concept of medical image fusion refers to the process of extracting and utilising information from several scans simultaneously in the analysis and diagnosis of patients. READ MORE

  4. 4. Environmental Applications of Aquatic Remote Sensing

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Petra Philipson née Ammenberg; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; Bildanalys; TECHNOLOGY Information technology Image analysis; TEKNIKVETENSKAP Informationsteknik Bildanalys; Computerized Image Analysis; datoriserad bildanalys;

    Abstract : Many lakes, coastal zones and oceans are directly or indirectly influenced by human activities. Through the outlet of a vast amount of substances in the air and water, we are changing the natural conditions on local and global levels. READ MORE

  5. 5. Hyperspectral Image Generation, Processing and Analysis

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hamed Hamid Muhammed; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY Information technology Image analysis; TEKNIKVETENSKAP Informationsteknik Bildanalys; Bildanalys; hyperspectral imaging; colour filter mosaics; remote sensing; crop reflectance; surface water quality; disease severity; plant density; linear system of equations; waste water detection; chlorophyll a; suspended paticulate matter; weighted fixed neural networks; weighted incremental neural networks; camera spectrometer; Bildanalys;

    Abstract : Hyperspectral reflectance data are utilised in many applications, where measured data are processed and converted into physical, chemical and/or biological properties of the target objects and/or processes being studied. It has been proven that crop reflectance data can be used to detect, characterise and quantify disease severity and plant density. READ MORE
