  1. 1. Material decomposition using a photon counting X-ray detector in low energy range

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Rasmus Solem; [2021]
    Keywords : Medicine and Health Sciences;

    Abstract : Material decomposition in X-ray imaging is used to separate different materials or elements in an image and to quantify their respective concentration. The material decomposition and quantification are made possible by the dependency of attenuation on the attenuating material and photon energy. READ MORE

  2. 2. Precise Detection of People Using Pre-Trained Machine Learning Models With Assisting Heat Sensor Camera

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Viktor Joelsson; Elias Rudberg; [2021]
    Keywords : Technology and Engineering;

    Abstract : The thesis examines the possibility of developing a system that can be used to detect the number of people in a given area with high accuracy. By using a variety of hardware components, publicly available object detection models and a cloud platform a highly modern approach is examined. READ MORE

  3. 3. Anomaly detection for automated security log analysis : Comparison of existing techniques and tools

    University essay from Linköpings universitet/Databas och informationsteknik

    Author : Måns Fredriksson Franzén; Nils Tyrén; [2021]
    Keywords : Security; Log analysis; Anomaly detection; Machine learning; Clustering;

    Abstract : Logging security-related events is becoming increasingly important for companies. Log messages can be used for surveillance of a system or to make an assessment of the dam- age caused in the event of, for example, an infringement. READ MORE

  4. 4. 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

  5. 5. Maximizing performance gain of Variable Rate Shading tier 2 while maintaining image quality : Using post processing effects to mask image degradation

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Fredrik Lind; Andrés Diaz Escalante; [2021]
    Keywords : Variable Rate Shading; VRS; Adaptive shading; Rendering optimization; Image based shading; Variable Rate Shading; VRS; Adaptiv skuggning; Renderingsoptimering; Bildbaserad skuggning;

    Abstract : Background. Performance optimization is of great importance for games as it constrains the possibilities of content or complexity of systems. Modern games support high resolution rendering but higher resolutions require more pixels to be computed and solutions are needed to reduce this workload. READ MORE
