  • 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 ...
  • 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 ...
