    Abstract : This thesis addresses a challenging problem: “how to let the visually impaired ‘see’ others emotions”. We, human beings, are heavily dependent on facial expressions to express ourselves. A smile shows that the person you are talking to is pleased, amused, relieved etc. READ MORE

  2. 2. Colour Correction of Underwater Images Using Spectral Data

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Julia Åhlén; Högskolan i Gävle.; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap; Colour; Correction; Attenuation; Coefficient; Underwater; TECHNOLOGY Information technology Image analysis; TEKNIKVETENSKAP Informationsteknik Bildanalys; Bildanalys; Bildanalys;

    Abstract : For marine sciences sometimes there is a need to perform underwater photography. Optical properties of light cause severe quality problems for underwater photography. Light of different energies is absorbed at highly different rates under water causing significant bluishness of the images. READ MORE

  3. 3. 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; datoriserad bildanalys; Computerized Image Analysis;

    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)).

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; Bildanalys; TECHNOLOGY Information technology Image analysis; TEKNIKVETENSKAP Informationsteknik Bildanalys; datoriserad bildanalys; Computerized Image Analysis;

    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

  5. 5. 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; datoriserad bildanalys; Computerized Image Analysis;

    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
