   Sammanfattning : In digital pathology, hematoxylin & eosin (H&E) is a routine stain which is performed on most clinical cases and it often provides clinicians with sufficient information for diagnosis. However, when making decisions on how to guide breast cancer treatment, immunohistochemical staining of human epidermal growth factor 2 (HER2 staining) is also needed. LÄS MER

4. 3. Noise Reduction of Scintillation Camera Images Using UNET: A Monte Carlo Simulation Approach

   Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

   Författare :Johanna Korpijärvi; [2021]
   Nyckelord :Medicine and Health Sciences;

   Sammanfattning : Background The project aims to reduce the noise in planar 111-In projections with a machine learning model. Method Sixteen base phantoms were used to create 696 phantoms in XCAT. An anterior planar projection was simulated with 111-In and ten uptake curves for each phantom in SIMIND. LÄS MER

5. 4. Deep Learning based Video Super- Resolution in Computer Generated Graphics

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Vinit Jain; [2020]
   Nyckelord :Deep Learning; Convolutional Neural Networks; Video Super-Resolution; Computer Generated Graphics; Gaming.; Deep Learning; Convolutional Neural Networks; Video Super-Resolution; Computer Generated Graphics; Gaming.;

   Sammanfattning : Super-Resolution is a widely studied problem in the field of computer vision, where the purpose is to increase the resolution of, or super-resolve, image data. In Video Super-Resolution, maintaining temporal coherence for consecutive video frames requires fusing information from multiple frames to super-resolve one frame. LÄS MER

7. 5. Performance Comparison of Image Enhancement Algorithms Evaluated on Poor Quality Images

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Sammanfattning : Many applications require automatic image analysis for different quality of the input images. In many cases, the quality of acquired images is suitable for the purpose of the application. However, in some cases the quality of the acquired image has to be modified according to needs of a specific application. LÄS MER
