    • An evaluation of PolSAR speckle filters on Compact-Pol images 

      Foucher, Samuel; Landry, Tom; López Martínez, Carlos; Charbonneau, François; Gagnon, Langis (IEEE, 2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The goal of this study is to evaluate some polarimetric speckle filters when applied to Compact Polarimetry (CP) data. Seven filters are evaluated on a set of artificial CP images. Performances regarding image restoration ...

    • Analysis, evaluation, and comparison of polarimetric SAR speckle filtering techniques 

      Foucher, Samuel; López Martínez, Carlos (2014-04)
      Article
      Accés restringit per política de l'editorial
      Speckle noise filtering on polarimetric SAR (PolSAR) images remains a challenging task due to the difficulty to reduce a scatterer-dependent noise while preserving the polarimetric information and the spatial information. ...

    • Exploitation of the additive component of the polarimetric noise model for speckle filtering 

      Foucher, Samuel; Farage, Grégory; López Martínez, Carlos (2010)
      Text en actes de congrés
      Accés obert
      Ratio filters for speckle noise reduction in SAR imagery are recursive filters where the image structure is iteratively recovered from an initial oversmoothed image. We show that the MBPolSAR filter could be interepreted ...

    • Low-level processing of PolSAR images with binary partition trees 

      Salembier Clairon, Philippe Jean; Foucher, Samuel; López Martínez, Carlos (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper discusses the interest of Binary Partition Trees (BPTs) and the usefulness of graph cuts for low-level processing of PolSAR images. BPTs group pixels to form homogeneous regions, which are hierarchically structured ...

    • Optimum graph cuts for pruning binary partition trees of polarimetric SAR images 

      Salembier Clairon, Philippe Jean; Foucher, Samuel (Institute of Electrical and Electronics Engineers (IEEE), 2016-09-01)
      Article
      Accés obert
      This paper investigates several optimum graph-cut techniques for pruning binary partition trees (BPTs) and their usefulness for the low-level processing of polarimetric synthetic aperture radar (PolSAR) images. BPTs group ...

    • Remote sensing image processing with graph cut of binary partition trees 

      Salembier Clairon, Philippe Jean; Foucher, Samuel (Instituto Politécnico Nacional, 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper discusses the interest of hierarchical region-based representations of images such as Binary Partition Trees (BPTs) and the usefulness of graph cut to process them. BPTs can be considered as an initial abstraction ...

    • The polarimetric ratio filter applied to polinsar images 

      Foucher, Samuel; López Martínez, Carlos; Charbonneau, François (IEEE, 2012)
      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 ...

    • Turbo speckle filtering applied to PolSAR data 

      Farage, Grégory; Foucher, Samuel; López Martínez, Carlos; Bénié, Goze B. (IEEE Computer Society Publications, 2008)
