  • Cyriac, Praveen; Bertalmío, Marcelo; Kane, David; Vazquez-Corral, Javier (Society of Photo Optical Instrumentation Engineers (SPIE), 2015)
    High dynamic range imaging techniques involve capturing and storing real world radiance values that span many orders of magnitude. However, common display devices can usually reproduce intensity ranges only up to two to ...
  • Zamir, Syed Waqas; Vazquez-Corral, Javier; Bertalmío, Marcelo (Society of Motion Picture & Television Engineers (SMPTE), 2017)
    Gamut mapping transforms colors of the original (image or video) content to the color palette of the display device with the simultaneous goals of (a) reproducing content accurately while preserving the artistic intent ...
  • Gil Rodríguez, Raquel; Vazquez-Corral, Javier; Bertalmío, Marcelo (Society of Motion Picture & Television Engineers (SMPTE), 2017)
    In cinema and TV it is quite usual to have to work with footage coming from several cameras, which show noticeable color differences among them even if they are all the same model. In TV broadcasts, technicians work in ...
  • Vazquez-Corral, Javier; Zamir, Syed Waqas; Bertalmío, Marcelo (S. Hirzel Verlag (SHV), 2014)
    Gamut reduction transforms the colors of an input image within the range of a target device. A good gamut reduction algorithm will preserve the experience felt by the viewer of the original image. Saliency algorithms ...
  • Galdran, Adrian; Vazquez-Corral, Javier; Pardo, David; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    We propose a novel image-dehazing technique based on the minimization of two energy functionals and a fusion scheme to combine the output of both optimizations. The proposed fusion-based variational image-dehazing (FVID) ...
  • Zamir, Syed Waqas; Vazquez-Corral, Javier; Bertalmío, Marcelo (Society of Photo Optical Instrumentation Engineers (SPIE), 2015)
    Wide gamut digital display technology, in order to show its full potential in terms of colors, is creating an opportunity to develop gamut extension algorithms (GEAs). To this end, in this work we present two contributions. ...
  • Vazquez-Corral, Javier; Zamir, Syed Waqas; Galdran, Adrian; Pardo, David; Bertalmío, Marcelo (The Society for Imaging Science and Technology (IS&T), 2016)
    The retinex theory of color vision has been a light of inspiration for color researchers since its inception 50 years ago. It has been adapted to work for different goals such as shadow removal, high dynamic range imaging, ...
  • Vazquez-Corral, Javier; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    We propose a method for the color stabilization of cinema shots coming from different cameras that use unknown logarithmic encoding curves. The log-encoding curves are approximated by a concatenation of gamma-curves, ...
  • Bertalmío, Marcelo; Vazquez-Corral, Javier (Color Science Association of Japan (CSAJ), 2015)
    Gamut mapping transforms the color of an input image within the range of a target device. A huge amount of research has been devoted to two subproblems that arise from this general one: gamut reduction and gamut extension. ...
  • Zamir, Syed Waqas; Vazquez-Corral, Javier; Bertalmío, Marcelo (Society of Motion Picture & Television Engineers (SMPTE), 2016)
    While wide color gamut (WCG) capabilities are a key element of emerging display and projection technologies, at present most image content is recorded using standards such as DCI-P3 for cinema or BT.709 for TV that have a ...
  • Gil Rodríguez, Raquel; Vazquez-Corral, Javier; Bertalmío, Marcelo (The British Machine Vision Association (BMVA), 2015)
    In this paper we present a novel approach to the problem of exposure fusion of a stack of pictures for the generation of high dynamic range (HDR) radiance maps. All exposure fusion approaches, when applied on 8-bit non-RAW ...
  • Galdran, Adrian; Vazquez-Corral, Javier; Pardo, David; Bertalmío, Marcelo (Springer, 2015)
    Images captured under adverse weather conditions, such as haze or fog, typically exhibit low contrast and faded colors, which may severely limit the visibility within the scene. Unveiling the image struc- ture under the ...
