  1. 1. Image-to-Image Translation for Improvement of Synthetic Thermal Infrared Training Data Using Generative Adversarial Networks

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Hanna Hamrell; [2021]
    Nyckelord :machine learning; deep learning; image-to-image translation; image processing; generative adversarial networks; infrared images; computer vision;

    Sammanfattning : Training data is an essential ingredient within supervised learning, yet time con-suming, expensive and for some applications impossible to retrieve. Thus it isof interest to use synthetic training data. However, the domain shift of syntheticdata makes it challenging to obtain good results when used as training data fordeep learning models.

  2. 2. Development of methods and software for rapid quality control in fluoroscopy

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Majid Khosamadi; [2021]
    Nyckelord :;

    Sammanfattning : Background: Fluoroscopy is a common imaging technique which uses X-ray to derive a real time imaging of patient anatomy to determine diagnosis and positioning of patients for interventional procedures. It is therefore important that the fluoroscopy systems maintain their performance. LÄS MER

  3. 3. Att drabbas av synskada som äldre : En kvalitativ intervjustudie

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för psykologi (PSY); Linnéuniversitetet/Institutionen för psykologi (PSY)

    Författare :Sarinti Nimpuno Christensen; Nathalie Petersen; [2021]
    Nyckelord :visual impairment; elderly; phenomenology; lifeworld; transformative learning; synskada; äldre; livsförändring; transformativt lärande; livsvärld;

    Sammanfattning : Syftet med föreliggande studie har varit att uppnå ökad förståelse för hur det upplevs att få en synskada i en sen ålder i livet, samt hur synskadade äldre hanterat denna livsförändring.  Studien utgick från semistrukturerade intervjuer av sex äldre personer med synskada i Danmark, som alla drabbats av grav synnedsättning efter att de fyllt 60 år.

  4. 4. Ensembles of Single Image Super-Resolution Generative Adversarial Networks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Victor Castillo Araújo; [2021]
    Nyckelord :Generative Adversarial Networks; Single Image Super-Resolution; Computer Vision; Convolutional Neural Networks; Ensemble Learning; Generative Adversarial Networks; Superupplösning; Datorseende; Bildanalys; Convolutional neural networks; Ensembler;

    Sammanfattning : Generative Adversarial Networks have been used to obtain state-of-the-art results for low-level computer vision tasks like single image super-resolution, however, they are notoriously difficult to train due to the instability related to the competing minimax framework. Additionally, traditional ensembling mechanisms cannot be effectively applied with these types of networks due to the resources they require at inference time and the complexity of their architectures.

  5. 5. Put the Light Where it is Needed

    Magister-uppsats, KTH/Ljusdesign

    Författare :Christofer Blixt; [2020]
    Nyckelord :Lighting Design Method for Urban Green Areas; Conceptual Design Proposal; Level of Contrast; Level of Light; Distribution of Light; Aesthetic Qualities; Perceived Safety;

    Sammanfattning : In this thesis I have analyzed how the phenomenon level of contrast, a consequence of the relation between level of light and distribution of light, works within urban green areas. For this particular site, the too high level of contrast is a result of the high level of light distributed 1) in the direction of oncoming pedestrians and 2) in a single zone of light and 3) on a too condensed surface area and 4) in a space with multiple vertical elements (in a dark space with low reflectance values).
