  1. 6. Processing of Optical Coherence Tomography Images : Filtering and Segmentation of Pathological Thyroid Tissue

    University essay from Linköpings universitet/Institutionen för medicinsk teknik; Linköpings universitet/Medicinska fakulteten

    Author : Daniela Koller; [2016]
    Keywords : ;

    Abstract : In the human body, the main function of the healthy thyroid gland is the regulation of the metabolism and hormone production. Included in the thyroid are organized structured and uniformly shaped follicles ranging from 50-500 μm in diameter. READ MORE

  3. 7. Detection of Pathological Lesions in High Resolution Retinal Images

    University essay from Tekniska högskolan; Medicinsk informatik

    Author : Frida Rosander; [2013]
    Keywords : ;

    Abstract : High resolution retinal cameras with adaptive optics makes it possible to image small structures in the eye, such as photoreceptors and nerve bres, as well as blood vessels. Adaptive optics was rst developed to reduce blur in stellar images, but has later been used to correct for ocular aberrations in order to achieved higher resolution in retinal images. READ MORE

  4. 8. Enhancement and Visualization of VascularStructures in MRA Images Using Local Structure

    University essay from Medicinsk informatik; Tekniska högskolan

    Author : Morteza Esmaeili; [2010]
    Keywords : Adaptive Filtering; Tubular Structure; 3D Filter; Enhancement; Local Structure;

    Abstract : The novel method of this thesis work is based on using quadrature filters to estimate an orientation tensor and to use the advantage of tensor information to control 3D adaptive filters. The adaptive filters are applied to enhance the Magnetic Resonance Angiography (MRA) images. READ MORE

  5. 9. Texture Classification by High Order Symmetry Derviatives of Gaussians

    University essay from Högskolan i Halmstad/Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Werner Pomwenger; [2003]
    Keywords : ;

    Abstract : In this master thesis we propose high order symmetry derivatives of gaussians for texture classification. The symmetry derivative approach is applied to a multiresolutional pyramid structure, which finally results in a more dimensional feature space represented by high order complex moments. READ MORE
