  1. 11. On the evaluation of print mottle

    Författare :Carl-Magnus Fahlcrantz; Jan-Olof Eklundh; Jon Hardeberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mottle; Print quality; Texture; Image analysis; Perception; Computer science; Datalogi;

    Sammanfattning : Print Mottle is perhaps one of the most disturbing factors influencing overall Print Quality. Mottle has traditionally been evaluated by estimating the reflectance variation in the print. LÄS MER

  3. 12. Efficient mineral liberation – Multidimensional investigation of mechanical stress and ore texture

    Författare :Parisa Semsari Parapari; Jan Rosenkranz; Mehdi Parian; Hakan Benzer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Loading mechanism; Ore texture; Breakage mode; Fracture energy; Fragmentation; Breakage mechanism; Statistical analysis; 3D Deformation; Crack quantification; Mineral Processing; Mineralteknik;

    Sammanfattning : Within mineral comminution, the product properties (such as particle size distribution and mineral liberation characteristics) along with process efficiency are affected by material related and process environment factors. Understanding and optimizing these factors leads to designing and developing an energy-efficient process with a specified product. LÄS MER

  4. 13. Homogenization of Reynolds equations and of some parabolic problems via Rothe's method

    Författare :Emmanuel Kwame Essel; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics;

    Sammanfattning : This PhD thesis is focussed on some problems of great interest in applied mathematics. More precisely, we investigate some new questions in homogenization theory, which have been motivated by some concrete problems in tribology. LÄS MER

  5. 14. Estimating Human Limb Motion Using Skin Texture and Particle Filtering

    Författare :Björn Holmberg; Håkan Lanshammar; Virgil Stokes; Christopher L. Vaughan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human motion analysis; Skin texture; Monte Carlo estimation; Particle filter; Mutual Information; Simulated Annealing; Marker-free; Rigid body transformation; 2D correlation; Systems engineering; Systemteknik;

    Sammanfattning : Estimating human motion is the topic of this thesis. We are interested in accurately estimating the motion of a human body using only video images capturing the subject in motion. Video images from up to two cameras are considered.The first main topic of the thesis is to investigate a new type of input data. LÄS MER

  7. 15. Applications of statistical methods in quantitative magnetic resonance imaging

    Författare :Patrik Brynolfsson; Anders Garpebring; Tufve Nyholm; Eirik Malinen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Quantitative imaging; tumor imaging; dynamic contrast-enhanced MRI; diffusion weighted MRI; texture analysis; radiofysik; radiation physics;

    Sammanfattning : Magnetic resonance imaging, MRI, offers a vast range of imaging methods that can be employed in the characterization of tumors. MRI is generally used in a qualitative way, where radiologists interpret the images for e.g. diagnosis, follow ups, or assessment of treatment response. LÄS MER
