Eigen Value and Eigen Vector Based Decomposition and Wishart Supervised Classification on Fully Polarimetric SAR Data

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...

An Unsupervised Classification Using Agglomerative Hierarchical Clustering, Wishart Test Statistic and the C-p Decomposition for Fully Polarimetric Sar Data

A new unsupervised classification algorithm is introduced for fully polarimetric SAR data. The agglomerative hierarchical algorithm and Wishart test statistics are used for the cluster segmentation, which includes the process of estimation the number of clusters. The Cloude-Pottier decomposition & HSI color transform are used for the target identification, which also automatically render the co...

Clustering by deterministic annealing and Wishart based distance measures for fully-polarimetric SAR-data

The basic assumption of clustering is that the observed data embodies a specific structure. This structure is represented by groups of data points, which are relativly isolated within the feature space. The goal of clustering is to find and represent this dissimilar groups of similar elements or, in other words, to subdivide the data space into a number of partitions. In this paper a spectral c...

Stokes Vector Based Polarimetric SAR Land Classification

Statistical eigen-inference from large Wishart matrices

The asymptotic behavior of the eigenvalues of a sample covariance matrix is described when the observations are from a zero mean multivariate (real or complex) normal distribution whose covariance matrix has population eigenvalues of arbitrary multiplicity. In particular, the asymptotic normality of the fluctuation in the trace of powers of the sample covariance matrix from the limiting quantit...
