1. 6. Virtual H&E Staining Using PLS Microscopy and Neural Networks

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Sally Vizins; Hanna Råhnängen; [2024]
   Nyckelord :Deep learning; Virtual staining; Skin tissue; Hematoxylin Eosin; H E; Pathology; Carcinoma; Point light source illumination; Neural Networks; GANs; Generative adversarial networks; CNNs; Convolutional neural networks; Relativistic generative adversarial network; Unet; Digital microscopy; Attention-Unet; Dense-Unet; Mathematics and Statistics;

   Sammanfattning : Histopathological examination, crucial in diagnosing diseases such as cancer, traditionally relies on time- and resource-consuming, poorly standardized chemical staining for tissue visualization. This thesis presents a novel digital alternative using generative neural networks and a point light source (PLS) microscope to transform unstained skin tissue images into their stained counterparts.

3. 7. Using Neural Radiance Fields and Gaussian Splatting for 3D reconstruction of aircraft inspections

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Roos Eline Bottema; [2024]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The rapid evolution of machine learning techniques has revolutionized computer vision, particularly with the introduction of Neural Radiance Fields (NeRF) and the optimization of 3D Gaussians for rendering novel scene views. These methods, such as NeRF and Gaussian Splatting, have demonstrated success in synthetic data scenarios with consistent lighting and well-captured scenes. LÄS MER

4. 8. Classifying femur fractures using federated learning

   Master-uppsats, Linköpings universitet/Statistik och maskininlärning

   Författare :Hong Zhang; [2024]
   Nyckelord :Atypical femur fracture; Federated Learning; Neural Network; Classification;

   Sammanfattning : The rarity and subtle radiographic features of atypical femoral fractures (AFF) make it difficult to distinguish radiologically from normal femoral fractures (NFF). Compared with NFF, AFF has subtle radiological features and is associated with the long-term use of bisphosphonates for the treatment of osteoporosis. LÄS MER

5. 9. Digital Twins and Sustainability: A Comprehensive Review of Limitations and Opportunities

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Simeon Petrov; [2023-12-04]
   Nyckelord :Digital Twins; Real Twin; Sustainability; Metrics; Indicators; Industry; Manufacturing; Production; Systemic Literature Review;

   Sammanfattning : During the past few years there has been an increasing push to deliver sustainable products and improve production processes to meet the growing demand faced by various types of industries. There is a high importance placed on identifying and defining project, product, and policy goals but sustainability goals within these areas are difficult to define. LÄS MER

7. 10. Image Quality Assessment Pipeline and Semi-Automated Annotation method for Synthetic Data

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Liam Le Tran; Edina Dedovic; [2023-10-24]
   Nyckelord :Facial Expression Recognition; FACS; Action Units; styleGAN2-ada; synthetic data; Image Quality Assessment; Multi-stage Pre-training; Pipeline Processing; Semi-automated Human Annotation;

   Sammanfattning : Predicting human emotions through facial expression, particularly in relation to medication field such as clinical trial settings, has garnered scientific interest in recent years due to significant understanding of the impact of treatment on emotions and social functioning. This thesis aims to improve performance of a FER model using large scale of synthetic data. LÄS MER
