1. 6. Development of Advanced X-ray Micro-Tomography Helical Scan andTomographic Data Processing

   University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

   Author : Yoseph Abraham; [2023]
   Keywords : ;

   Abstract : 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). READ MORE

3. 7. Procedural Natural Texture Generation on a Global Scale

   University essay from Linköpings universitet/Informationskodning

   Author : Anna Pohl Lundgren; [2023]
   Keywords : computer graphics; procedural generation; procedural textures; gpu; image processing; satellite imagery; real time; real-time; shadow detection;

   Abstract : This Master’s thesis investigates the application of dynamically generated procedural terrain textures for texturing 3D representations of the Earth’s surface. The study explores techniques to overcome limitations of the currently most common method – projecting satellite imagery onto the mesh – such as insufficient resolution for close-up views and challenges in accommodating external lighting models.

4. 8. Image and RADAR fusion for autonomous vehicles

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Xavier de Gibert Duart; [2023]
   Keywords : Image; Camera; Computer Vision; Data Fusion; Sensors; 3D data processing; Point Clouds; Calibration; MATLAB and RADAR; RADAR; kamera; datorseende; datafusion; sensorer; 3D-databehandling; punktmoln; kalibrering; MATLAB Image;

   Abstract : Robust detection, localization, and tracking of objects are essential for autonomous driving. Computer vision has largely driven development based on camera sensors in recent years, but 3D localization from images is still challenging. Sensors such as LiDAR or RADAR are used to compute depth; each having its own advantages and drawbacks. READ MORE

5. 9. Computer-Aided Characterization of Lung - Segmentation and Vessel Tree Analysis Algorithms for Clinical Research Applications

   University essay from KTH/Fysik

   Author : Daniel Karoumi; [2023]
   Keywords : Lung; lung segmentation; NSIP; IPF; lung vessels; lung morphometry; 3D Slicer; Lunga; lungsegmentering; NSIP; IPF; lungkärl; lung morfometri; 3D Slicer;

   Abstract : The initial stage of a lung examination involves the segmentation of a CT image, a process that has been put under a lot of pressure with the high demand for chest scans and accurate segmentations. Current automatic segmentation algorithms are either non-robust for different datasets, not easily accessible, or time-consuming. READ MORE

6. 10. CHARACTERIZATION AND EVALUATION OF A NIPAM POLYMER GEL MRI DOSIMETER SYSTEM

   University essay from

   Author : Christian Waldenberg; [2022-11-08]
   Keywords : Medical physics; Normoxic polymer gel dosimeter; NiPAM;

   Abstract : Purpose: The normoxic polymer gel dosimeter based on N-isopropyl acrylamide (NiPAM) is a promising full 3D-dosimeter with high spatial resolution and near tissue equivalency. However, limited work have been done in vestigating this dosimeter. The dose response and reproducibility of a NiPAM dosimeter was investigated. READ MORE
