  1. 1. Network Orientation and Segmentation Refinement Using Machine Learning

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Michael Nilsson; Jonatan Kentson; [2023]
    Keywords : deep learning; semantic segmentation; orientation learning; road networks; retina networks;

    Abstract : Network mapping is used to extract the coordinates of a network's components in an image. Furthermore, machine learning algorithms have demonstrated their efficacy in advancing the field of network mapping across various domains, including mapping of road networks and blood vessel networks.

  3. 2. Image Segmentation and Object Identification in Cancer Tissue Slides from Fluorescence Microscopy

    University essay from Uppsala universitet/Avdelningen Vi3

    Author : Sebastian Eriksson; Fredrik Forsberg; [2023]
    Keywords : image analysis; cancer research; fluorescent microscopy; image segmentation; bildanalys; cancerforskning; fluorescensmikroskopi; bildsegmentering;

    Abstract : In cancer research, there is a need to make accurate spatial measurements in multi-layered fluorescence microscopy images. Researchers would like to measure distances in and between biological objects such as nerves and tumours, to investigate questions which includes if nerve distribution in and around tumours can have a prognostic value in cancer diagnostics.

  4. 3. Real-time Autofocus Algorithm in Laser Speckle Contrast Imaging

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Giovanni Russo; [2023]
    Keywords : Laser speckle contrast imaging; Autofocus; Blind image sharpness assessment; Speckle noise; Perimed’s Perfusion Speckle Imager;

    Abstract : Microcirculation is defined as the blood flow in the smallest blood vessels. Laser speckle contrast imaging (LSCI) is a full field imaging technique that provides instantaneous 2-D perfusion maps of illuminated tissues based on speckle contrast. READ MORE

  5. 4. Riskfaktorer för Strongylus vulgaris – en enkätstudie

    University essay from SLU/Dept. of Clinical Sciences

    Author : Jessica Lernå; [2023]
    Keywords : Strongylus vulgaris; blodmask; stor blodmask; häst; avmaskning; riskfaktorer;

    Abstract : I stort sett exponeras alla betande hästar för endoparasiter någon gång under sin levnad. Strongylus vulgaris, en av hästens stora blodmaskar, anses vara den hästparasit som är mest patogen och kan orsaka skador som är direkt fatala. Strongylus vulgaris har en fekal-oral livscykel som tar cirka sex till sju månader att fullborda. READ MORE

  6. 5. Reconstruction of Accelerated Cardiovascular MRI data

    University essay from Linköpings universitet/Statistik och maskininlärning
