  • Gamonal, Ferran P.; Ballester, Coloma; Haro Ortega, Gloria; Meinhardt Llopis, Enric; Palomares, Roberto P. (Editor Image Processing On Line, 2019)
    We present a detailed analysis of FALDOI, a large displacement optical flow method proposed by P. Palomares et al. This method requires a set of discrete matches, which can be extremely sparse, and an energy functional ...
  • Meinhardt Llopis, Enric (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We propose an edge detector based on the selection of well/ncontrasted pieces of level lines, following the proposal of/nDesolneux-Moisan-Morel (DMM) [1]. The DMM edge detector/nhas the problem of over-representation, that ...
  • Palomares, Roberto P.; Meinhardt Llopis, Enric; Ballester, Coloma; Haro Ortega, Gloria (Springer, 2017)
    We propose a large displacement optical flow method that introduces a new strategy to compute a good local minimum of any optical flow energy functional. The method requires a given set of discrete matches, which can be ...
  • Meinhardt Llopis, Enric (Universitat Pompeu Fabra, 2011-05-16)
    Aquesta tesi proposa una estructura de dades per emmagatzemar imatges tridimensionals. L'estructura da dades té forma d'arbre i codifica les components connexes dels conjunts de nivell de la imatge. Aquesta estructura ...
  • Sadek, Rida; Constantinopoulos, Constantinos; Meinhardt Llopis, Enric; Ballester, Coloma; Caselles, Vicente (SIAM (Society for Industrial and Applied Mathematics), 2012)
    Using a classical result on algebraic invariants of the unimodular group, we present in this paper some basic geometric affine invariant quantities, and we use them to construct some distinctive descriptors for object ...
  • Raad, Lara; Oliver Parera, Maria; Ballester, Coloma; Haro Ortega, Gloria; Meinhardt Llopis, Enric (IPOL, 2020)
    This work describes two anisotropic optical flow inpainting algorithms. The first one recovers the missing flow values using the Absolutely Minimizing Lipschitz Extension partial differential equation (also called infinity ...
