  1. 1. Exploring Normalizing Flow Modifications for Improved Model Expressivity

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

    Författare :Marcel Juschak; [2023]
    Nyckelord :Normalizing Flows; Motion Synthesis; Invertible Neural Networks; Glow; MoGlow; Maximum Likelihood Estimation; Generative models; normaliserande flöden; rörelsesyntes; inverterbara neurala nätverk; Glow; MoGlow; maximum likelihood-skattning generativa modeller;

    Sammanfattning : Normalizing flows represent a class of generative models that exhibit a number of attractive properties, but do not always achieve state-of-the-art performance when it comes to perceived naturalness of generated samples. To improve the quality of generated samples, this thesis examines methods to enhance the expressivity of discrete-time normalizing flow models and thus their ability to capture different aspects of the data.

  3. 2. Geo-Enabling Piste Maps Using Anchor Points

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

    Författare :Lou-Lou Pei; [2021]
    Nyckelord :Georeferencing; Positioning; Coordinate Transformations; Piste maps; Geografiska referenspunkter; Positionering; Koordinattransformationer; Pistkartor;

    Sammanfattning : Piste maps have been used as navigational aids by winter sports enthusiasts for decades. These maps are often hand drawn and are designed to be visually pleasing while still providing an overview of the terrain of a ski resort. LÄS MER

  4. 3. Similarity models for atlas-based segmentation of whole-body MRI volumes

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Elin Axberg; Ida Klerstad; [2020]
    Nyckelord :Atlas-based segmentation; image registration; image similarity measures;

    Sammanfattning : In order to analyse body composition of MRI (Magnetic Resonance Imaging) volumes, atlas-based segmentation is often used to retrieve information from specific organs or anatomical regions. The method behind this technique is to use an already segmented image volume, an atlas, to segment a target image volume by registering the volumes to each other. LÄS MER

  5. 4. Eigen-birds : Exploring avian morphospace with image analytictools

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för teknikvetenskaper

    Författare :Mikael Thuné; [2012]
    Nyckelord :image analysis; eigen-birds; eigen; principal component analysis; pca; birds; avian; warping; biharmonic splines; affine transformation;

    Sammanfattning : The plumage colour and patterns of birds have interested biologists for a long time.Why are some bird species all black while others have a multitude of colours? Does ithave anything to do with sexual selection, predator avoidance or social signalling?Many questions such as these have been asked and as many hypotheses about thefunctional role of the plumage have been formed.

  7. 5. High-speed View Matching using Region Descriptors

    Master-uppsats, Bildbehandling

    Författare :Anders Lind; [2010]
    Nyckelord :Object Recognition; Region; RANSAC; MSCR; MSER; SIFT; GPU; CUDA;

    Sammanfattning : This thesis treats topics within the area of object recognition. A real-time view matching method has been developed to compute the transformation between two different images of the same scene. LÄS MER
