F. Chatelain, J.-Y. Tourneret, J. Inglada
2008 IEEE Transactions on Image Processing  
These distributions referred to as multisensor multivariate gamma distributions (MuMGDs) are potentially interesting for detecting changes in SAR images acquired by different sensors having different numbers  ...  This paper studies a family of distributions constructed from multivariate gamma distributions to model the statistical properties of multisensor synthetic aperture radar (SAR) images.  ...  Section II recalls important results on monosensor multivariate gamma distributions (MoMGDs). Section III defines the family of MuMGDs considered for change detection in multisensor SAR images.  ...

Classification of oyster habitats by combining wavelet-based texture features and polarimetric SAR descriptors

O. Regniers, L. Bombrun, I. Ilea, V. Lafon, C. Germain
2015 2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS)  
In this study, we propose to evaluate the potential of combining very high resolution optical and SAR images for the classification of oyster habitats in tidal flats.  ...  This demonstrate the benefit of using both optical and SAR data for oyster habitats mapping in tidal flats.  ...  Therefore, in addition to texture features computed from optical data, descriptors derived from VHR SAR data are used and a multisensor fusion scheme is proposed to enhance the mapping accuracy.  ...

SAR image segmentation using generalized pairwise Markov chains

Stephane Derrode, Wojciech Pieczynski, Sebastiano B. Serpico
2003 Image and Signal Processing for Remote Sensing VIII  
We will compare the PMC model with respect to the HMC one for the unsupervised segmentation of SAR images, for both Gaussian distributions and Pearson system of distributions.  ...  The efficiency of Markov models in the context of SAR image segmentation mainly relies on their spatial regularity constraint.  ...  Multisensor and multiresolution images can still be segmented using HMC 5, 6 .  ...

Conditional Copulas for Change Detection in Heterogeneous Remote Sensing Images

G. Mercier, G. Moser, S.B. Serpico
2008 IEEE Transactions on Geoscience and Remote Sensing  
In a previous study, it was proven that the local statistics of the images acquired at the two dates could be used to extract a relevant change indicator.  ...  Then, usual Kullback-Leibler-based comparisons of those statistics are applied to define a change measure, which may be analyzed (e.g., by thresholding) in order to detect changes.  ...  ACKNOWLEDGMENT The authors would like to thank CNES for the validation of ground truth and for the ERS and SPOT images, under the contract Détection de Changements Abrupts (DéCA, Project RI-022), which  ...
