1. 1. Robust Object Recognition and Tracking with Drones

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Jiaying Wu; [2024]
   Nyckelord :;

   Sammanfattning : The Skara Skyddsängel project explores an innovative method of providing illumination for cyclists along a 20km unlit bike lane using drones. Current GNSS approach performs generally well but further improvements are need for better robustness. Consequently, this thesis project is raised to seek a robust solution in the field of computer vision. LÄS MER

3. 2. 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.

4. 3. Influence of Varying Electric Light Distribution on Melanopic Equivalent Daylight Illuminance and Lighting Energy Use

   Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

   Författare :Rebecka Ståhl; Parvathy Biju; [2023]
   Nyckelord :Alertness; Circadian Entrainment; Clear Sky; Correlated Colour Temperature; Daylighting; Direct Electric Lighting; Direct-Indirect Electric Lighting; Energy-Efficiency; Grasshopper; Integrative Lighting; LARK 2.0; Melanopic Equivalent Daylight Illuminance; Overcast Sky; Photopic Illuminance; Spectral Power Distribution.; Technology and Engineering;

   Sammanfattning : Human beings in modern society spend more than 90% of their time indoors to live, work, and socialize. To improve health, quality of life and task performance, integrative lighting is designed to give the right light at the right time at the eye to stimulate circadian entrainment. LÄS MER

5. 4. Particle Detection in Bone Marrow Using CNNs and Transformer Networks

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Anna Källén; Marcus Williams; [2023]
   Nyckelord :Bone Marrow; Dark Field Microscopy; Fourier Ptychography; Machine Learning; Convolutional Neural Networks; Transformer Networks; Quantisation; Technology and Engineering;

   Sammanfattning : The critical role of hematological stem cells, concentrated in bone marrow, in disease diagnosis makes the detection of these cells an imperative task. The current process, however, is slow and heavily reliant on expert interpretation, underscoring the need for automation. LÄS MER

7. 5. Virtual Staining of Blood Cells using Point Light Source Illumination and Deep Learning

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Joel Wulff; [2022]
   Nyckelord :Deep learning; virtual staining; blood; cells; GANs; Generative adversarial networks; CNNs; convolutional neural networks; ESRGAN; Unet; digital microscopy; Mathematics and Statistics;

   Sammanfattning : Blood tests are an important part of modern medicine, and are essentially always stained using chemical colorization methods before analysis by computational or manual methods. The staining process allows different parts of blood cells to be discerned that would be unnoticeable in unstained blood. LÄS MER
