Optimum Ensemble Classification for Fully Polarimetric SAR Data Using Global-Local Classification Approach
In this paper, a proposed ensemble classification for fully polarimetric synthetic aperture radar (PolSAR) data using a global-local classification approach is presented. In the first step, to perform the global classification, the training feature space is divided into a specified number of clusters. In the next step to carry out the local classification over each of these clusters, which cont...
متن کاملDecomposition Methods for the Estimation of Bare Soil Moisture Using Fully Polarimetric Sar Data
Soil moisture plays a critical role in the surface energy balance at the soil-atmosphere interface [4]. Using radar backscattering to retrieve soil moisture is a method of major concern due to its sensitivity to soil moisture [14] [15].In the past decades, many empirical, semi-empirical and physical models that relate the measured 0 to volumetric soil moisture mv have been carried out[14][15]. ...
متن کاملInvestigation of fully polarimetric TerraSAR-X data for soil parameters estimation
The potential of estimating soil moisture from fully polarimetric satellite X-band SAR data is analysed for the first time. The Physical Optics model has been combined with an azimuthally rotation distribution, forming a socalled Extend-PO-model (X-PO), for the scattering process representation which includes a cross-polarized component. In addition, the eigen-based decomposition approach has b...
متن کاملWeighted Pyramid Linking for Segmentation of Fully-polarimetric Sar Data
Image segmentation has the general goal to define regions within an image, in which all pixels have similiar properties. For fullypolarimetric SAR data this is often done by spectral classification without any use of spatial information. On the contrary the proposed method aims to find homogenous segments in the image, which should be compact and connected if possible. A multiresolution image p...
متن کاملFully Polarimetric Sar Data for Oil Slick Observation
In this study a fully polarimetric electromagnetic model for sea surface Mueller matrix is exploited, under low to moderate wind conditions, to design and experiment a Synthetic Aperture Radar (SAR) oil slick filter. The latter is simple and computer time effective. Experiments, accomplished over C-band Multi Look Complex (MLC) SIR-C/X-SAR data and L-band Single Look Complex (SLC) ALOS PalSAR d...
