Modelling PolSAR Scattering Signatures at Long Wavelengths of Glacier Ice Volumes [PDF]

open access: yes, 2012
The crucial role of cryosphere for understanding the global climate change has been widely recognized in recent decades [1]. Glaciers and ice sheets are the main components of the cryosphere and constitute the basic reservoir of fresh water for high ...

Machine learning classification based on k-Nearest Neighbors for PolSAR data

open access: yesAnais da Academia Brasileira de Ciências
In this work, we focus on obtaining insights of the performances of some well-known machine learning image classification techniques (k-NN, Support Vector Machine, randomized decision tree and one based on stochastic distances) for PolSAR (Polarimetric ...

Statistical Classification for Heterogeneous Polarimetric SAR Images

open access: yes, 2011
International audienceThis paper presents a general approach for high-resolution polarimetric SAR data classification in heterogeneous clutter, based on a statistical test of equality of covariance matrices. The Spherically Invariant Random Vector (SIRV)

Segmentation of polsar images

open access: yes, 2017
This project will implement a segmentation algorithm for PolSAR images to represent the boundaries of the areas in the image and the regions. Identifying the regions on SAR images can be useful for further analysis, for example, to classify the elements of the image.
