  1. 21. Segmentation of x-ray images using deep learning trained on synthetic data

    University essay from KTH/Fysik

    Author : Marcus Larsson; [2023]
    Keywords : Radiography; Deep Learning; Synthetic Data; Segmentation; Röntgen; Djupinlärning; Syntetisk Data; Segmentering;

    Abstract : Radiograph examinations play a critical role in various applications such as the detection of bone pathologies and lung cancer, despite the challenge of false negatives. The integration of Artificial Intelligence (AI) holds promise in enhancing image quality and assisting radiologists in their diagnostic processes. READ MORE

  3. 22. Skyline Delineation for Localization in Occluded Environments : Improved Skyline Delineation using Environmental Context from Deep Learning-based Semantic Segmentation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Kyle William Coble; [2023]
    Keywords : Skyline delineation; Skyline detection; Semantic segmentation; Terrain based navigation; Digital elevation models; Uncrewed surface vessel; Planetary exploration robots; Horisont avgränsning; Horisont upptäckt; Semantisk segmentering; Terrängbaserad navigering; Digitala höjdmodeller; Obemannat ytfartyg; Planetariska utforskningsrobotar;

    Abstract : This thesis addresses the problem of improving the delineation of skylines, also referred to as skyline detection, in occluded and challenging environments where existing skyline delineation methods may struggle or fail. Delineated skylines can be used in monocular camera localization methods by comparing delineated skylines to digital elevation model data to estimate a position based on known terrain. READ MORE

  4. 23. Semi-Supervised Domain Adaptation for Semantic Segmentation with Consistency Regularization : A learning framework under scarce dense labels

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Daniel Morales Brotons; [2023]
    Keywords : Domain Adaptation; Semi-Supervised Learning; Semi-Supervised Domain Adaptation; Semantic Segmentation; Consistency Regularization; Domain Adaptation; Semi-Supervised Learning; Semi-Supervised Domain Adaptation; Semantisk Segmentering; Konsistensregularisering;

    Abstract : Learning from unlabeled data is a topic of critical significance in machine learning, as the large datasets required to train ever-growing models are costly and impractical to annotate. Semi-Supervised Learning (SSL) methods aim to learn from a few labels and a large unlabeled dataset. READ MORE

  5. 24. Computer-Aided Characterization of Lung - Segmentation and Vessel Tree Analysis Algorithms for Clinical Research Applications

    University essay from KTH/Fysik

    Author : Daniel Karoumi; [2023]
    Keywords : Lung; lung segmentation; NSIP; IPF; lung vessels; lung morphometry; 3D Slicer; Lunga; lungsegmentering; NSIP; IPF; lungkärl; lung morfometri; 3D Slicer;

    Abstract : The initial stage of a lung examination involves the segmentation of a CT image, a process that has been put under a lot of pressure with the high demand for chest scans and accurate segmentations. Current automatic segmentation algorithms are either non-robust for different datasets, not easily accessible, or time-consuming. READ MORE

  6. 25. The role of gap junctions in coordination of intercellular Ca2+ signaling

    University essay from KTH/Tillämpad fysik

    Author : Emma Latron; [2023]
    Keywords : applied physics; biophysics; Calcium; MDCKII; Gap Junctions; signalling; Segmentation; Tillämpad fysik; Biofysik; Kalcium; MDCKII; Gap Junctions; signalering; segmentering;

    Abstract : Calcium ions are one of the most versatile signalling molecules. They are essential tothe proper functioning of various cellular processes in many different types of cells.The calcium signals have been studied in the past using ratiometric dyes like Fura-2. READ MORE
