  • Color matching images with unknown non-linear encodings
    Gil Rodríguez, Raquel; Vazquez-Corral, Javier; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    We present a color matching method that, given two different views of the same scene taken by two cameras with unknown settings and unknown internal parameter values, and encoded with unknown non-linear curves, is able to ...
  • Color stabilization for multi-camera light-field imaging
    Vu-Thanh, Olivier; Canham, Trevor; Vazquez-Corral, Javier; Gil Rodríguez, Raquel; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    By capturing a more complete rendition of scene light than standard 2D cameras, light-field technology represents an important step towards closing the gap between live action cinematography and computer graphics. Light-field ...
  • Color-matching shots from different cameras having unknown gamma or logarithmic encoding curves
    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 ...
  • Digital camera colour processing pipeline for high dynamic range imaging and colour stabilisation for cinema
    Gil Rodríguez, Raquel (Universitat Pompeu Fabra, 2018-12-18)
    In this thesis we focus on two different image processing challenges: high dynamic range (HDR) image/video generation, and colour matching. In both cases, we redefine these tasks by taking into account the prior knowledge ...
  • High quality video in high dynamic range scenes from interlaced dual-ISO footage
    Gil Rodríguez, Raquel; Bertalmío, Marcelo (The Society for Imaging Science and Technology (IS&T), 2016)
    In this paper we present a simple and affordable method to generate high quality video from a high dynamic range scene. It is performed without utilizing extra lighting, neither alternating exposures, nor operating with ...
  • Issues with common assumptions about the camera pipeline and their impact in hdr imaging from multiple exposures
    Gil Rodríguez, Raquel; Vazquez-Corral, Javier; Bertalmío, Marcelo (SIAM (Society for Industrial and Applied Mathematics), 2019)
    Multiple-exposure approaches for high dynamic range (HDR) image generation share a set of building assumptions: that color channels are independent and that the camera response function (CRF) remains constant while changing ...
  • Issues with common assumptions about the camera pipeline, and their impact in HDR imaging from multiple exposures
    Gil Rodríguez, Raquel; Vazquez-Corral, Javier; Bertalmío, Marcelo (SIAM (Society for Industrial and Applied Mathematics), 2019)
    Multiple-exposure approaches for high dynamic range (HDR) image generation share a set of building assumptions: that color channels are independent and that the camera response function (CRF) remains constant while changing ...
  • The intrinsic error of exposure fusion for HDR imaging, and a way to reduce it
    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 ...
