  • Ferradans Ramonde, Sira; Bertalmío, Marcelo; Provenzi, Edoardo; Caselles, Vicente (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    Tone Mapping is the problem of compressing the range of a High-Dynamic Range image so that it can be displayed in a Low-Dynamic Range screen, without losing or introducing novel details: The final image should produce in ...
  • Ballester, Coloma; Bertalmío, Marcelo; Caselles, Vicente; Garrido Ostermann, Luis; Marques, Adrián; Ranchin, Florent (Institute of Electrical and Electronics Engineers (IEEE), 2007)
    Video is usually acquired in interlaced format, where each image frame is composed of two image fields, each field holding same parity lines. However, many display devices require progressive video as input; also, many ...
  • Bertalmío, Marcelo (Frontiers Media, 2014)
    There are many ways in which the human visual system works to reduce the inherent redundancy of the visual information in natural scenes, coding it in an efficient way. The non-linear response curves of photoreceptors and ...
  • Ferradans Ramonde, Sira; Bertalmío, Marcelo; Caselles, Vicente (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    Demosaicking is a particular case of interpolation problems where, from a scalar image in which each pixel has either the red, the green or the blue component, we want to interpolate the full-color image. State-of-the-art ...
  • Vazquez-Corral, Javier; Connah, David; Bertalmío, Marcelo (MDPI, 2014)
    Color camera characterization, mapping outputs from the camera sensors to an independent color space, such as XY Z, is an important step in the camera processing pipeline. Until now, this procedure has been primarily ...
  • Vazquez-Corral, Javier; Bertalmío, Marcelo (MDPI, 2014)
    It has now been 20 years since the seminal work by Finlayson et al. on the use of spectral sharpening of sensors to achieve diagonal color constancy. Spectral sharpening is still used today by numerous researchers for ...
