1. Fine-Tuning Parameters in CT
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : Computed tomography (CT) is a medical imaging technique that usesX-rays to obtain a reconstruction of an object. The term acquisition ge-ometry refers to the arrangement of imaging sensors and the X-ray sourceas well as the procedure used for data collection. LÄS MER
2. Structure from Motion with a Neural Network
Master-uppsats, Lunds universitet/Matematik LTHSammanfattning : This project delves into the 3D reconstruction of both single and multiple rigid motions, examining the potential of deep learning methods, such as that proposed by Moran et al., to supplant traditional geometry-based approaches. The project is structured into two main parts. LÄS MER
3. Development of Advanced X-ray Micro-Tomography Helical Scan andTomographic Data Processing
Master-uppsats, Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskapSammanfattning : 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
4. Surface Reconstruction using Multipath Propagation in Indoor MIMO Radar
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : Using active radar for localization in indoor environments is challenging. By signal reflection off walls and other static objects, false targets occur, referred to as multipath "ghosts". These are a significant hinder in interpreting the data. LÄS MER
5. Streamlining 3D City Modeling for Urban Flow Simulations by Automatic Integration of Multisource Topography
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : In the workflow of computational fluid dynamics, geometry preparation is commonly the most time-consuming step. For a fast CFD simulation, automatic surface reconstruction to obtain 3D city models for a chosen area is essential. To address this need, a literature study was conducted to map available data suitable for 3D city models. LÄS MER
