  • A novel linear feature detector for SAR images 

    He, Chu; Liao, Z.X.; Yang, Fang; Deng, Xinping; Liao, M.S. (2012-11-12)
    Article
    Open Access
    A new linear feature detector for synthetic aperture radar (SAR) images is presented in this article by embedding a three-region filter into the wedgelet analysis framework. One of its main features is that it can detect ...
  • A physical analysis of polarimetric SAR data statistical models 

    Deng, Xinping; López Martínez, Carlos; Varona, Eduardo Makhoul (Institute of Electrical and Electronics Engineers (IEEE), 2016-01-08)
    Article
    Open Access
    The random walk model is studied with the objective to obtain a physical explanation for the texture of polarimetric synthetic aperture radar (SAR) data. A simulator is designed to imitate the scattering process under ...
  • Bilateral distance based filtering for polarimetric SAR data 

    Alonso González, Alberto; López Martínez, Carlos; Salembier Clairon, Philippe Jean; Deng, Xinping (2013-10-30)
    Article
    Open Access
    This paper introduces a non-linear Polarimetric SAR data filtering approach able to preserve the edges and small details of the data. It is based on exploiting the data locality in both, the spatial and the polarimetric ...
  • Higher order statistics for texture analysis and physical interpretation of polarimetric SAR data 

    Deng, Xinping; López Martínez, Carlos (2016-07-01)
    Article
    Open Access
    The logarithmic cumulants (log-cumulants for short) of the second and third orders are widely used in the statistical analysis of polarimetric synthetic aperture radar (PolSAR) data. However, both the product model and the ...
  • Road extraction from SAR imagery based on multiscale geometric analysis of detector responses 

    He, Chu; Liao, Z.X.; Yang, Fang; Deng, Xinping; Liao, M.S. (2012)
    Article
    Restricted access - publisher's policy
    In this paper, a road network grouping algorithm for Synthetic Aperture Radar (SAR) images is proposed by exploiting multiscal e geometric analysis of detector responses. Before running the algorithm, a response map made ...
  • Statistical modeling of polarimetric SAR data: a survey and challenges 

    Deng, Xinping; López Martínez, Carlos; Chen, Jinsgon; Han, Pengpeng (2017-04-01)
    Article
    Open Access
    Knowledge of the exact statistical properties of the signal plays an important role in the applications of Polarimetric Synthetic Aperture Radar (PolSAR) data. In the last three decades, a considerable research effort has ...
  • Stereoscopic road network extraction by decision-level fusion of optical and SAR imagery 

    He, Chu; Yang, Fang; Yin, Sha; Deng, Xinping; Liao, Mingsheng (2013)
    Article
    Restricted access - publisher's policy
    A new stereoscopic road network extraction framework based on the decision-level fusion of optical and Synthetic Aperture Radar (SAR) imagery is proposed in this paper. Three steps are included in this framework: 1) road ...
  • Texture analysis and physical interpretation of polarimetric SAR data 

    Deng, Xinping (Universitat Politècnica de Catalunya, 2016-07-26)
    Doctoral thesis
    Open Access
    This thesis is dedicated to the study of texture analysis and physical interpretation of PolSAR data. As the starting point, a complete survey of the statistical models for PolSAR data is conducted. All the models are ...
  • The use of the L2-norm for the analysis of texture on PolSAR data 

    Deng, Xinping; López Martínez, Carlos (VDE-Verlag, 2016)
    Conference lecture
    Restricted access - publisher's policy
    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 ...
