Abstract :
PolInSAR data is a good example of a high dimensional SAR data. A blind filtering of these data does not make use of possible constraints imposed by the scattering process. In this paper it is shown that the scattering over forested areas induces some constrains on the data that can be fruitfully exploited to improve the final filtering, with que consequent improved of the quantitative estimation process.
