1. 1. Deep Learning for Point Detection in Images

   Master-uppsats, Linköpings universitet/Datorseende

   Författare :Björn Runow; [2020]
   Nyckelord :Deep learning; Point detection; U-Net; UNet ; HRNet; FCN; Weighted Hausdorff distance; EU-pallet; Computer vision;

   Sammanfattning : The main result of this thesis is a deep learning model named BearNet, which can be trained to detect an arbitrary amount of objects as a set of points. The model is trained using the Weighted Hausdorff distance as loss function. BearNet has been applied and tested on two problems from the industry. LÄS MER

3. 2. Clinical evaluation of atlas based segmentation for radiotherapy of prostate tumours

   Master-uppsats, Institutionen för fysik

   Författare :Christoffer Granberg; [2011]
   Nyckelord :segmentation; registration; radiotherapy; atlas;

   Sammanfattning : Abstract   Background Semi-automated segmentation using deformable registration of atlases consisting of pre-segmented patient images can facilitate the tedious task of delineating structures and organs in patients subjected to radiotherapy planning. However, a generic atlas based on a single patient may not function well enough due to the anatomical variation between patients. LÄS MER
