1. 1. Anatomical segmentation of the human brain: comparative assessment of two automatic methods

   Master-uppsats,

   Författare :Carl von Dorrien; [2023-08-22]
   Nyckelord :Medical physics; MAPER; FreeSurfer; FastSurfer; Automatic brain segmentation; MRI; Deep Neural Network; Brain;

   Sammanfattning : Magnetic Resonance Imaging (MRI) is a robust and versatile imaging modality and an integral component of a lot of studies, especially when performing quantitative analysis. MRI is the preferred method of imaging the brain because of its excellent soft tissue contrast. LÄS MER

3. 2. Network Orientation and Segmentation Refinement Using Machine Learning

   Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

   Författare :Michael Nilsson; Jonatan Kentson; [2023]
   Nyckelord :deep learning; semantic segmentation; orientation learning; road networks; retina networks;

   Sammanfattning : Network mapping is used to extract the coordinates of a network's components in an image. Furthermore, machine learning algorithms have demonstrated their efficacy in advancing the field of network mapping across various domains, including mapping of road networks and blood vessel networks.

4. 3. Analyzing the Influence of Synthetic andAugmented Data on Segmentation Model

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Alex Peschel; [2023]
   Nyckelord :Artificial Intelligence; Microorganisms; Segmentation; Synthesizing; Augmentation;

   Sammanfattning : The field of Artificial Intelligence (AI) has experienced unprecedented growth in recent years, thanks to the numerous applications related to speech recognition, natural language processing, and computer vision. However, one of the challenges facing AI is the requirement for large amounts of energy, time, and data to be effective and accurate. LÄS MER

5. 4. Subsidized employment and the symbolic segmentation of internal markets: An interview study with Swedish workers on wage subsidies on navigating dual labor markets.

   Master-uppsats, Lunds universitet/Socialhögskolan

   Författare :Alexander Fäldtman; [2023]
   Nyckelord :wage subsidy; dual labor market; disability; criminal record; interactionism; Social Sciences;

   Sammanfattning : The aim of the study was to complement dual labor market research by qualitatively exploring how labor market segmentations may be understood beyond sociodemographics or inequalities of job quality. By interviewing 12 Swedish workers with wage subsidies I have found that access to high job quality may facilitate trajectories towards primary market sectors, but they are only relevant so far as the workers feel that they deserve access to good jobs.

7. 5. Automation of forest road inventory using computer vision and machine learning

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Jacques de Flon; [2023]
   Nyckelord :Computer vision; Machine Learning; Image recognition; forestry; road inventory; pothole; gravel road;

   Sammanfattning : There are around 300, 000 kilometer of gravel roads throughout the Swedish countryside, used every day by common people and companies. These roads face constant wear due to harsh weather as well as from heavy traffic, and thus, regular maintenance is required to keep up the road standard. LÄS MER
