  2. 1. Mathematical Methods for Image Based Localization

    Author : Klas Josephson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Multiple View Geometry; Image Based Localization; Computer Vision; Gröbner Basis; Minimal Problems;

    Abstract : The underlying question in localization is, where am I? In this thesis a purely image based approach is proposed to solve this problem. In order to create a complete image based system, there are many subproblems that have to be addressed. The localization problem can also be solved in other ways, for example, with a GPS. READ MORE

  4. 2. Image-based numerical modelling of heterogeneous materials

    Author : Robert Auenhammer; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray computed tomography; image analysis; image-based modelling; Composites;

    Abstract : In science there has always been a desire to visualise the invisible. Since the discovery of X-rays in 1895, imaging research has made remarkable progress. Nowadays, state-of-the-art technology allows to visualise the micro-structure of objects in three dimensions. However, merely visualising the structure is often insufficient. READ MORE

  5. 3. On Aortic Blood Flow Simulations : Scale-Resolved Image-Based CFD

    Author : Jonas Lantz; Matts Karlsson; Shawn Shadden; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis focuses on modeling and simulation of the blood flow in the aorta, the largest artery in the human body. It is an accepted fact that abnormal biological and mechanical interactions between the blood flow and the vessel wall are involved in the genesis and progression of cardiovascular diseases.

  6. 4. Image-based multi-omics data integration : Exploring whole-body PET/MRI, -omics data and body composition

    Author : Robin Visvanathar; Håkan Ahlström; Joel Kullberg; Jan Eriksson; Katrine Riklund; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Body composition; Imiomics; genomics; metabolomics; MRI; PET; insulin sensitivity; T2D;

    Abstract : Advanced body composition analysis with whole-body imaging could uncover novel associations between regional tissue composition and metabolic disease. Imiomics is an automated image analysis framework that enables large-scale integration of magnetic resonance imaging (MRI) data and orthogonal technologies such as metabolomics and genomics for the detailed study of body composition.

  7. 5. Computational Methods for Image-Based Spatial Transcriptomics

    Author : Axel Andersson; Carolina Wählby; Anna Klemm; Filip Malmberg; Karl Åström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spatial omics; Spatial transcriptomics; Spatial biology; In Situ Sequencing; Visualization; Spatial statistics; Fluorescence microscopy; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Why does cancer develop, spread, grow, and lead to mortality? To answer these questions, one must study the fundamental building blocks of all living organisms — cells. Like a well-calibrated manufacturing unit, cells follow precise instructions by gene expression to initiate the synthesis of proteins, the workforces that drive all living biochemical processes.
