      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper, the processing of temporal PolSAR image series is addressed through a region-based and multi-scale data representation, the Binary Partition Tree (BPT). This structure contains useful information related ...
    • The polarimetric ratio filter applied to polinsar images

      Text en actes de congrés
      Accés restringit per política de l'editorial
      We are proposing recursive filter for the filtering of Single Look Complex PolInSAR data. This recursive filter allows the iterative refinement of a coarse multilook estimate by reintroducing details that have been ...
    • The use of the L2-norm for the analysis of texture on PolSAR data 

      Deng, Xinping; López Martínez, Carlos (VDE-Verlag, 2016)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      The use of the l2-norms of the scattering vectors is suggested to texture analysis of PolSAR data, with the benefits that neither we need to analyze the polarimetric channels separately, nor we need to filter the data to ...
