    Keywords : ;

    Abstract : Climate change is generally considered one of the most prominent issues of the 21stcentury and resources from many fields of science are used on researching the topicand finding solutions. Computer science and social science are two fields that havecombined over the last ten years to study the topic. READ MORE

  3. 12. Semantic segmentation using convolutional neural networks to facilitate motion tracking of feet : For real-time analysis of perioperative microcirculation images in patients with critical limb thretening ischemia

    University essay from Linköpings universitet/Avdelningen för medicinsk teknik

    Author : Andreas Öberg; Martin Hulterström; [2021]
    Keywords : semantic segmentation; convolutional neural network; critical limb threatening ischemia; ROI tracking; deep learning;

    Abstract : This thesis investigates the use of Convolutional Neural Networks (CNNs) toperform semantic segmentation of feet during endovascular surgery in patientswith Critical Limb Threatening Ischemia (CLTI). It is currently being investigatedwhether objective assessment of perfusion can aid surgeons during endovascularsurgery. READ MORE

  4. 13. Semantic Segmentation of Iron Ore Pellets in the Cloud

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Hampus Lindberg; [2021]
    Keywords : Data annotation; Semantic segmentation; Docker; AWS; SageMaker; Ilastik; PyTorch; Unet ;

    Abstract : This master's thesis evaluates data annotation, semantic segmentation and Docker for use in AWS. The data provided has to be annotated and is to be used as a dataset for the creation of a neural network. Different neural network models are then to be compared based on performance. READ MORE

  5. 14. Statistics and machine learning for classification of emotional and semantic content of EEG

    University essay from Lunds universitet/Teknisk matematik (CI); Lunds universitet/Institutionen för reglerteknik

    Author : David Ohlin; Oskar Keding; [2021]
    Keywords : Technology and Engineering;

    Abstract : Interpreting EEG measurements is of great relevance, both for developing underlying neuroscientific theory and improving existing applications. In this study, two networks with different approaches to time-frequency analysis and feature selection are compared on simulated and real data for semantic and emotional perception. READ MORE

  6. 15. Convolutional neural networks for semantic segmentation of FIB-SEM volumetric image data

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Fredrik Skärberg; [2020-11-26]
    Keywords : Deep learning; convolutional neural networks; image analysis; semantic segmentation; focused ion beam scanning electron microscopy; porous materials; controlled drug release;

    Abstract : Focused ion beam scanning electron microscopy (FIB-SEM) is a well-established microscopy technique for 3D imaging of porous materials. We investigate three porous samples of ethyl cellulose microporous films made from ethyl cellulose and hydroxypropyl cellulose (EC/HPC) polymer blends. READ MORE
