  1. 1. Local Features for Range and Vision-Based Robotic Automation

    Författare :Fredrik Viksten; Robert Forchheimer; Achim Lilienthal; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Local features; object pose estimation; range data; Image analysis; Bildanalys;

    Sammanfattning : Robotic automation has been a part of state-of-the-art manufacturing for many decades. Robotic manipulators are used for such tasks as welding, painting, pick and place tasks etc. LÄS MER

  3. 2. Local symmetry features in image processing

    Författare :Josef Bigün; Olivier Fangeras; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The extraction of features is necessary for all aspects of image processing and analysis such as classification, segmentation, enhancement and coding. In the course of developing models to describe images, a need arises for description of more complex structures than lines. LÄS MER

  4. 3. Local spatio-temporal image features for motion interpretation

    Författare :Ivan Laptev; KTH; []
    Nyckelord :computer vision; motion; recognition; scale-space;

    Sammanfattning : Visual motion carries information about the dynamics of ascene. Automatic interpretation of this information isimportant when designing computer systems forvisualnavigation, surveillance, human-computer interaction, browsingof video databases and other growing applications.

  5. 4. Local structure and composition : in additively manufactured bulk metallic glasses and composites

    Författare :Inga Katharina Goetz; Jochen M. Schneider; Björgvin Hjörvarsson; Ulf Jansson; Maria Teresa Pérez Prado; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; additive manufacturing; bulk metallic glasses; nanoscale clustering; convective flow; laser nitriding; laser powder bed fusion; metallic glass - ceramic composites; oxygen impurities; mechanical properties; magnetic properties; viscosity; Fysik; Physics;

    Sammanfattning : Additive manufacturing enables the production of complex multi-material geometries and bulk metallic glass parts beyond their critical casting thickness. The local modification of structure, composition, and properties is explored in this thesis with the aim to design novel composite materials and functional gradients. LÄS MER

  7. 5. Methods for material parameter estimation : global and local approach

    Författare :Göran Lindkvist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The rapid development of computing technology has made powerful tools, such as finite element codes, available for more and more companies. The use of simulation tools, predictive engineering, is a prerequisite today in product development. LÄS MER
