      Fidjestøl, Svein (Master thesis, 2005)
      This thesis covers the topic of image processing in relation to the segmentation and analysis of pores protruding the surface in the three dimensional surface structure of paper. The successful analysis of pores is related ...

    • Fast Seeded Region Growing in a 3D Grid 

      Lorentzen, Erlend Andreas (Master thesis, 2011)
      The purpose of this thesis was to examine ways to adapt common 2D segmentation techniques to work with 3D grids. The focus of the thesis became how to automate and improve the performance of region growing in 3D grids. ...

    • Individual fiber segmentation of three-dimensional microtomograms of paper and fiber-reinforced composite materials 

      Bache-Wiig, Jens; Henden, Per Christian (Master thesis, 2005)
      The structure of a material is of special significance to its properties, and material structure has been an active area of research. In order to analyze the structure based on digital microcopy images of the material, ...

    • Isosurface Extraction and Visualisation of Binary 3D X-Ray Images of Fibre Structures 

      Tubaas, Terje (Master thesis, 2005)
      In this master thesis, the use of an isosurface extraction technique on binary 3D x-ray micro-tomographic images of paper fibres has been examined. Traditionally, volume rendering has been used to visualise the images. In ...

    • Multimodal Volume to Volume Registration between Ultrasound and MRI 

      Ryen, Tommy (Master thesis, 2006)
      This master-thesis considers implementation of automated multimodal volume-to-volume registration of images, in order to provide neurosurgeons with valuable information for planning and intraoperative guidance. Focus has ...

    • Quantified is simplified; Treating the spatial entropy as continuous for prognostics of early ovarian cancer 

      Geithus, Håvard Malm (Master thesis, 2013)
      A substantial number of studies have proven that analysing the texture of DNA-specific stained cancer cell nuclei can provide robust and reliable prognostic information. Such information is important to make a qualified ...

    • Realtime capture and streaming of gameplay experiences 

      Amlie, Kristian (Master thesis, 2007)
      Today's games are social on a level that could only be imagined before. With modern games putting a stronger emphasis on social networking than ever before, the identity in the game often becomes on par with the one in ...

    • Reduksjon av bildedata ved identifisering av menneskeskapte objekter 

      Nordseth, Tor (Master thesis, 2005)
      Algoritmen i oppgaven bruker egenskapsidentifisering til å finne deler av landskapsbilder som inneholder menneskeskapte objekter. Bildene er tatt i det infrarøde spekteret og viser varmestrålingen fra landskapet. Ut ifra ...

    • Segmentation of Kidneys from MR-Images 

      Ree, Eirik (Master thesis, 2005)
      Det har blitt utviklet en metode for semi-automatisk segmentering av nyrer fra 2D og 3D MR-bilder. Algoritmen foregår som en kombinasjon av en watershed segmentering og en modellbasert segmentering. For å løse problemet ...

    • Segmentation of Medical Images Using CBR 

      Rieck, Christian Marshall (Master thesis, 2007)
      This paper describes a case based reasoning system that is used to guide the parameters of a segmentation algorithm. Instead of using a fixed set of parameters that gives the best average result over all images, the ...
