  • 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 ...
  • Igual, Laura; Preciozzi, Javier; Garrido, Luís; Almansa, Andrés; Caselles, Vicente; Rougé, Bernard (AIMS American Institute of Mathematical Sciences, 2007)
    In this work we propose a new automatic methodology for computing accurate digital elevation models (DEMs) in urban environments from low baseline stereo pairs that shall be available in the future from a new kind of earth ...
  • Facciolo Furlan, Gabriele; Arias, Pablo; Caselles, Vicente; Sapiro, Guillermo (Springer, 2009)
    A nonlocal variational formulation for interpolating a sparsel sampled image is introduced in this paper. The proposed variational formulation, originally motivated by image inpainting problems, encourages the transfer ...
  • 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 ...
  • Facciolo Furlan, Gabriele; Almansa, Andrés; Aujol, Jean-François; Caselles, Vicente (SIAM (Society for Industrial and Applied Mathematics), 2009)
    We propose a restoration algorithm for band limited images that considers irregular (perturbed) sampling, denoising, and deconvolution. We explore the application of a family of regularizers that allow to control the ...
