  1. 6. A Global Linear Optimization Framework for Adaptive Filtering and Image Registration

    Författare :Gustaf Johansson; Hans Knutsson; Mats Andersson; Klas Nordberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Global Linear Optimization; Linear Optimization; Regularization; Medical Image Registration; Structure Tensor;

    Sammanfattning : Digital medical atlases can contain anatomical information which is valuable for medical doctors in diagnosing and treating illnesses. The increased availability of such atlases has created an interest for computer algorithms which are capable of integrating such atlas information into patient specific dataprocessing. LÄS MER

  3. 7. Robust Visual Object Tracking mean shift, particle filters and point features

    Författare :Zulfiqar Hasan Khan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PF; MSEPF; mean shift; visual object tracking; RANSAC; SIFT; SURF;

    Sammanfattning : Visual object tracking has been identified as a promising technique for many computer vision applications like surveillance, flight navigation, video compression and driver assistance. The main idea is to find the state ofthe object and how it changes over time, in recursive video frames. LÄS MER

  4. 8. Dynamics of Magnetic Molecules under Electrical Control

    Författare :Henning Hammar; Jonas Fransson; Annica M. Black-Schaffer; Alexander Shnirman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular magnets; Spin dynamics; Non-adiabatic effects; Exchange interaction; Thermoelectricity; Fysik; Physics;

    Sammanfattning : This thesis theoretically studies the dynamics of molecular magnets under electrical control. Molecular magnets are nanoscale magnets that can, e.g., consist of single-molecules or single-atoms. LÄS MER

  7. 10. Ion Tracks for Micro- and Nanofabrication : From Single Channels to Superhydrophobic Surfaces

    Författare :Reimar Spohr; Lars Westerberg; Lars Montelius; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ion track; single ion; real time; phase detection; conductometric cell; conductometry; electro replication; microtechnology; nanotechnology; surfactant; self organization; GMR; magnetic; sensor technology; hydrophobic; tilted texture.; Physics; Fysik; Materialvetenskap; Materials Science;

    Sammanfattning : A method is described for preset-count irradiations between 1 and 100 ions singling-out individual ions from an ion beam with more than a billion ions arriving per second. The ion tracks are etched in a conductometric system with real-time evaluation of the acquired data. The etch process can be interrupted when reaching a preset channel diameter. LÄS MER
