• Bidirectional Reflectance Measurement and Reflection Model Fitting of Complex Materials Using an Image-Based Measurement Setup 

      Sole, Aditya Suneel; Farup, Ivar; Nussbaum, Peter; Tominaga, Shoji (Journal article; Peer reviewed, 2018)
      Materials with a complex visual appearance, like goniochromatic or non-diffuse, are widely used for the packaging industry. Measuring optical properties of such materials requires a bidirectional approach, and therefore, ...
    • Evaluating an image based multi-angle measurement setup using different reflection models 

      Sole, Aditya Suneel; Farup, Ivar; Nussbaum, Peter (Journal article; Peer reviewed, 2017)
      Image based measurement setups are widely used for multidirectional reflectance measurements of materials. Different reflection models are used to estimate the material reflectance. In this paper we use two commonly ...
    • Evaluating an image-based bidirectional reflectance distribution function measurement setup 

      Sole, Aditya Suneel; Farup, Ivar; Nussbaum, Peter; Tominaga, Shoji (Journal article; Peer reviewed, 2018)
      We evaluate an image-based multiangle bidirectional reflectance distribution function measurement setup by comparing it to measurements from two commercially available goniospectrophotometers. The image-based setup uses ...
    • Image Content and Hand Writing Analysis of the Dead Sea Scrolls 

      Dale, Erik; Fjørkenstad, Håvard Østli; Pursley, Yeshi Jampel (Bachelor thesis, 2022)
      Institutt for informasjonssikkerhet og kommunikasjonsteknologi (IIK) ved Norges teknisk-naturvitenskapelige universitet (NTNU) i Gjøvik ønsket en måte å automatisk ta ut informasjon, for eksempel bokstaver, fra Dødehavsrullene, ...
    • Image-Based Bidirectional Reflectance Measurement of Non-Diffuse and Gonio-Chromatic Materials 

      Sole, Aditya Suneel (Doctoral theses at NTNU;2019:344, Doctoral thesis, 2019)
      Visual appearance of packaging material can vary in terms of perceived colour or lightness properties with a change in illumination and viewing directions mainly due to its optical properties. This gives a desirable visual ...
    • Measurement and rendering of complex non-diffuse and goniochromatic packaging materials 

      Sole, Aditya Suneel; Guarnera, Giuseppe Claudio; Farup, Ivar; Nussbaum, Peter (Peer reviewed; Journal article, 2020)
      Realistic renderings of materials with complex optical properties, such as goniochromatism and non-diffuse reflection, are difficult to achieve. In the context of the print and packaging industries, accurate visualisation ...
    • On the Acquisition and Reproduction of Material Appearance 

      Sole, Aditya Suneel; Gigilashvili, Davit; Midtfjord, Helene B.; Guarnera, Dar'ya; Guarnera, Giuseppe Claudio; Thomas, Jean-Baptiste; Hardeberg, Jon Yngve (Chapter, 2019)
      Currently, new technologies (e.g. 2.5D and 3D printing processes) progress at a fast pace in their capacity to (re)produce an ever-broader range of visual aspects. At the same time, a huge research effort is needed to ...

    • Optimized light source spectral power distribution for RGB camera based spectral reflectance recovery 

      Wang, Lixia; Sole, Aditya Suneel; Hardeberg, Jon Yngve; Wan, Xiaoxia (Peer reviewed; Journal article, 2021)
      The accuracy of recovered spectra from camera responses mainly depends on the spectral estimation algorithm used, the camera and filters selected, and the light source used to illuminate the object. We present and compare ...
    • Simulator for Lokførerskolen 

      Ip, Marco; Karpowicz, Michael-Angelo; Kragset, Julian (Bachelor thesis, 2022)
      DeskSim er et togsimuleringsprogram skapt i jMonkeyEngine av Lokførerskolen, som har formålet å lære studenter prinsippene av togkunduktering gjennom å gi dem et tryggt miljø hvor de kan få førstehånds erfaring. Vi ble ...
