• 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 ...
    • Perceived Glossiness: Beyond Surface Properties 

      Gigilashvili, Davit; Thomas, Jean-Baptiste; Pedersen, Marius; Hardeberg, Jon Yngve (Journal article; Peer reviewed, 2019)
      Gloss is widely accepted as a surface- and illuminationbased property, both by definition and by means of metrology. However, mechanisms of gloss perception are yet to be fully understood. Potential cues generating gloss ...
    • Spatial Nonuniformity of Color Features in Projection Displays: A Quantitative Analysis 

      Thomas, Jean-Baptiste; Bakke, Arne Magnus; Gerhardt, Jérémie (Journal article; Peer reviewed, 2010)
      In this article, the authors investigate and study the color spatial uniformity of projectors. A common assumption in previous works is to consider that only the luminance is varying along the spatial dimensions. The authors ...
    • Spectral Adaptation Transform for Multispectral Constancy 

      Khan, Haris Ahmad; Thomas, Jean-Baptiste; Hardeberg, Jon Yngve; Laligant, Olivier (Journal article; Peer reviewed, 2018)
      The spectral reflectance of an object surface provides valuable information of its characteristics. Reflectance reconstruction from multispectral image data is typically based on certain assumptions. One of the common ...
    • Towards highlight based illuminant estimation in multispectral images 

      Khan, Haris Ahmad; Thomas, Jean-Baptiste; Hardeberg, Jon Yngve (Journal article; Peer reviewed, 2018)
      We review the physics based illuminant estimation methods, which extract information from highlights in images. Such highlights are caused by specular reflection from the surface of dielectric materials, and according to ...
