    • Filter array based spectral imaging : Demosaicking and design considerations 

      Wang, Xingbo (Doctoral thesis at NTNU;2016;, Doctoral thesis, 2016)
      Spectral imaging apparatus in current use are often cumbersome, costly and slow in operation, which becomes a major obstacle to extensive use of spectral imaging in several application areas. In recent years, the technical ...

    • An inverse display color characterization model based on an optimized geometrical structure 

      Thomas, Jean-Baptiste; Colantoni, Philippe; Hardeberg, Jon Yngve; Foucherot, Irene; Gouton, Pierre (Proceedings of SPIE;6807, Journal article; Peer reviewed, 2008)
      We have defined an inverse model for colorimetric characterization of additive displays. It is based on an optimized three-dimensional tetrahedral structure. In order to minimize the number of measurements, the structure ...

    • Multispectral imaging: narrow or wide band filters? 

      Wang, Xingbo; Thomas, Jean-Baptiste; Hardeberg, Jon Yngve; Gouton, Pierre (Journal article; Peer reviewed, 2014)
      In every aspect, spectral characteristics of filters play an important role in an image acquisition system. For a colorimetric system, traditionally, it is believed that narrow-band filters give rise to higher accuracy ...

    • 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 ...
