1. 1. An evaluation study of 3D imaging technology as a tool to estimate body weight and growth in dairy heifers

   Master-uppsats, SLU/Dept. of Animal Nutrition and Management

   Författare :Emelie Ahlberg; [2024]
   Nyckelord :body measurement; body weight; growth; heifer; three-dimensional imaging; young stock management;

   Sammanfattning : The aim of this thesis was to evaluate the use of a 3D camera as a tool to estimate body weight and growth in dairy heifers. Data collection lasted from October 2022 to January 2023 and was performed at the Swedish Livestock Research Centre in Uppsala, Sweden. LÄS MER

3. 2. Detection of local motion artifacts and image background in laser speckle contrast imaging

   Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

   Författare :Johannes Nyhlén; Märta Sund; [2023]
   Nyckelord :laser speckle contrast imaging; lsci; multi exposure laser speckle contrast imaging; melsci; machine learning; deep learning; statistical analysis; detection; local motion artifacts; 1D; 2D; 3D;

   Sammanfattning : Laser speckle contrast imaging (LSCI) and its extension, multi-exposure laser speckle contrast imaging (MELSCI) are non-invasive techniques to monitor peripheral blood perfusion. One of the main drawbacks of LSCI and MELSCI in clinical use is that the techniques are sensitive to tissue movement. LÄS MER

4. 3. Development of Advanced X-ray Micro-Tomography Helical Scan andTomographic Data Processing

   Master-uppsats, Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

   Författare :Yoseph Abraham; [2023]
   Nyckelord :;

   Sammanfattning : Micro-computed tomography (Micro-CT) is an imaging technique that allows for high-resolution,three-dimensional (3D) internal visualization of small objects in a non-destructive manner. However,a significant limitation arises when attempting to image elongated samples at higher resolutions andmagnifications due to the inherently small field of view (FOV). LÄS MER

5. 4. Optimization-Based Geometry Correction Of Blood Flow CFD Simulations Using 4D-Flow Data

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Fritiof Hegardt; [2022]
   Nyckelord :Technology and Engineering;

   Sammanfattning : 4D-flow is a powerful tool capable of capturing 3-dimensional, time-resolved flow measurements of blood flow in the body. Their current use is limited by resolution and scan times. A proposed solution is to use Simulation Based Imaging (SBI). LÄS MER

7. 5. Deep Learning Based Focus lnterpolation for Whole Slide Images

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Davis Nicmanis; [2022]
   Nyckelord :;

   Sammanfattning : Whole slide imaging is a crucial component of digital pathology, which emulates conventional microscopy by scanning the entire microscope slide. It results in a large digital image that can be examined by a cytopathologist or used in further computer-assisted image analysis. LÄS MER
