   Sammanfattning : In biology, many different kinds of microscopy are used to study cells. There are many different kinds of transmission microscopy, where light is passed through the cells, that can be used without staining or other treatments that can harm the cells. LÄS MER

4. 3. Exploiting Sparse Structures in Source Localization and Tracking

   Författare :Maria Juhlin; Matematisk statistik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Source localization; Cramér-Rao bounds; Convex Optimization;

   Sammanfattning : This thesis deals with the modeling of structured signals under different sparsity constraints. Many phenomena exhibit an inherent structure that may be exploited when setting up models, examples include audio waves, radar, sonar, and image objects. LÄS MER

5. 4. Comparison and Tracking Methods for Interactive Visualization of Topological Structures in Scalar Fields

   Författare :Himangshu Saikia; Tino Weinkauf; Filip Sadlo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; topology; scalar fields; merge tree; tree comparison; tracking; similarity search; Computer Science; Datalogi;

   Sammanfattning : Scalar fields occur quite commonly in several application areas in both static and time-dependent forms. Hence a proper visualization of scalar fieldsneeds to be equipped with tools to extract and focus on important features of the data. LÄS MER

7. 5. Laser Sheet Imaging and Image Analysis for Combustion Research

   Författare :Rafeef Abu-Gharbieh; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear diffusion filtering; optically dense sprays; curve evolution propagation; image sequence analysis; laser induced fluorescence; geodesic paths; level sets; LIF; optical density; spray characterization; flame propagation; laser; particle image velocimetry; spectroscopy; combustion engines; spray diagnostics; Mie scattering; flame fronts; laser attenuation; tracking; combustion diagnostics; curve matching; combustion; laser sheet imaging; PIV; time resolved imaging; segmentation;

   Sammanfattning : This Thesis presents techniques that aim at exploiting the potential of image analysis and processing in order to solve problems of data reduction, interpolation, quantification, and interpretation within the field of experimental laser imaging of combustion processes. Combustion is the most important source of energy for power generation, heating, and transportation in the world today and its strong dominance is projected to continue in the foreseeable future.
