  • Facciolo Furlan, Gabriele; Arias Martínez, 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/nthe transfer ...
  • Ballester, Coloma; Bertalmío, Marcelo; Caselles, Vicente; Sapiro, Guillermo; Verdera, Joan (Institute of Electrical and Electronics Engineers (IEEE), 2001)
    A variational approach for filling-in regions of missing data in digital images is introduced. The approach is based on joint interpolation of the image gray levels and gradient/isophotes directions, smoothly extending in ...
  • Caselles, Vicente; Sapiro, Guillermo; Solé, Andrés; Ballester, Coloma (SIAM (Society for Industrial and Applied Mathematics), 2006)
    A geometric representation for images is studied in this work. This is based on two complementary geometric structures for the topographic representation of an image. The first one computes a description of the Morse ...
