  1. 1. Skogens egenskaper på lavmark & dess förändring inom renskötselområdet : baserat på riksskogstaxeringsdata

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Oscar Andersson; Johan Persson; [2023]
    Nyckelord :Lav; Marklav; Cladonia spp; Lavmark; Renskötselområdet; Renskötsel; Rennäring; Skogsbruk; Skog; Egenskaper; Skogsegenskaper;

    Sammanfattning : Skogsbruket och renskötseln verkar idag på samma marker, vilka nyttjas för råvara och som betesmark. Renskötseln är beroende av skogar med bottenskikt av lav- eller lavrik typ då marklav är en essentiell födotillgång för renen vintertid. LÄS MER

  3. 2. Enhancing Simulated Sonar Images With CycleGAN for Deep Learning in Autonomous Underwater Vehicles

    Master-uppsats, KTH/Matematisk statistik

    Författare :Aron Norén; [2021]
    Nyckelord :Deep Learning; Machine Learning; Sonar; Simulation; GAN; cycleGAN; YOLO-v4; Data Sparsity; Uncertainty Estimations; Djupinlärning; maskininlärning; sonar; simulering; GAN; cycleGAN; YOLO-v4; gles data; osäkerhetsanalys;

    Sammanfattning : This thesis addresses the issues of data sparsity in the sonar domain. A data pipeline is set up to generate and enhance sonar data. The possibilities and limitations of using cycleGAN as a tool to enhance simulated sonar images for the purpose of training neural networks for detection and classification is studied. LÄS MER

  4. 3. Real versus Simulated data for Image Reconstruction : A comparison between training with sparse simulated data and sparse real data

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

    Författare :Aïssata Maiga; Johanna Löv; [2021]
    Nyckelord :Event based camera; image reconstruction; simulated data; real data; FireNet; E2VID; Event based camera; image reconstruction; simulated data; real data; FireNet; E2VID;

    Sammanfattning : Our study investigates how training with sparse simulated data versus sparse real data affects image reconstruction. We compared on several criteria such as number of events, speed and high dynamic range, HDR. The results indicate that the difference between simulated data and real data is not large. LÄS MER

  5. 4. An evaluation of U-Net’s multi-label segmentation performance on PDF documents in a medical context

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

    Författare :Fredrik Sebek; [2021]
    Nyckelord :U-Net; SS-U-Net; MultiResUNet; Portable; Document; Format; PDF; Segmentation; Multi-label; Conversion; U-Net; SS-U-Net; MultiResUNet; Bärbart; Dokumentformat; PDF; Segmentering; Konvertering;

    Sammanfattning : The Portable Document Format (PDF) is an ideal format for viewing and printing documents. Today many companies store their documents in a PDF format. However, the conversion from a PDF document to any other structured format is inherently difficult. LÄS MER

  7. 5. Deflection measurements with 3D close range photogrammetry

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Guillaume Defromont; [2021]
    Nyckelord :Photogrammetry; Computer Science; Optimization; Aero-elasticity; Fotogrammetry; Datvetenskap; Aeroelasticitet;

    Sammanfattning : Photogrammetry is a great technology to check and track deformations on anysurface. This information is critical in many tranportation industries such as aeronautics and the automotive industry. In this thesis report photogrammetry measurements were done using 2 Aicon cameras providing 3D targets coordinates. LÄS MER
